Introduction
I have played and leveled 11 free ($0 dollars spent) accounts from level 1 to 80 using various leveling techniques and unit combinations. From my experiences I tended to gravitate towards leveling key units because of how fast and efficient they made the experience of grinding through to the point where I can comfortably do dailies, clear challenges, pass Immortal Beast, and do most (if not all) event missions. Which is ultimately the goal of all Aigis players.
All this experience culminated into my DMM account (where I have spent some money on). Even when pulling in premium units I found myself relying on most of the follow S and A tier units as the core of my formation. Whether I am clearing the ‘Far-East’ story missions, tackling the very difficult ‘Magic City’ themed story missions, or attempting 7+ stamina Event missions.
All in all, this is purely from my own experiences. Others will have different play styles and most of the time that completely hinges on your shrine luck. But I hope this serves as a good general guideline one can follow.
Keeping with the 'free' theme, the list will focus exclusively on free units, trading post units, and Gold and below premium units. Side note: you can absolutely clear all (events included) of the current missions available to us with Gold and under units.
Hope this helps those who are seeking a 'direction' for leveling their formation.

Breakdown
S Tier
These are your core units. They take priority as units you would want to level, class change, and 100% affection first. These units will be useful no matter what point you are at in them game. Whether trying to clear ‘Gate Defense’ for the first time or tackling a ‘G’ tier event map. As your army evolves some of these units might be replaced on your primary team but will always find room as a sub. Another thing to note is the fact that these units are all free.
I want to go as far as to say that 6 out of 7 times when you begin a mission Katie will be the first unit you place. Unit reinforcement is the most important skill in the game, bar none. Unit deployment cost balancing is integral to the gameplay. Being able to deploy powerful units earlier will open up new tactics and placements, as well as making missions clears exponentially easier.
Iris is a no brainer. The healer is the single most important unit. Iris being a free gold tier healer will elevate her to being your primary healer over Allyssa in no time. Even in the future if you manage to acquire higher tier healers (of which there are only 3 at the moment) she will serve you well as a secondary or third string healer (there are more maps that require 3+ healers than you think, especially in the near future).
Leanne might be a curious choice to many but she is the only free heavy armor you get. She is statistically superior to both Benard and Garrett when it comes to defense. And that is what you are supposed to get from heavies in the first place. One of the core tactics of the game is the heavy + mage unit combo. There is not a single more potent and efficient combo in the game in the general sense. The direct upgrade to Leeane is Bernice. Even if you manage to pull Bernice (or in extreme cases, Gellius or Deine) Leeanne will always find a place as a sub. There will be many opportunities and missions that will require using 2 or more heavies.
Archers are your core range dps choice. Daniela completely outclasses all Archers below Platinum by a wide margin. She is free and you get a ton of copies of her. She is easy to level, and if you are willing to wager a bit of your future you can cost reduce her as well. Almost all Silver-only guides to clearing missions include Daniela. Demonstrates how capable of a unit she is.
A Tier
These units are high priority units. A few units are no-brainers but there are a few curious choices.
First off, Bernice and Pallis would be S-tier. However, them not being ‘free’ makes them A-tier. I would definitely classify them as A+.
Pallis is the best non-Platinum mage. She is superior to all male mages in DPS (skill included) and being a Silver unit, easier to level and pull from the shrine than Mehlis. If there is an event where she is a drop on a specific mission map you should try to get her. Being part of the mage-heavy core tactic makes her a core unit as well.
Bernice is a powerful and ‘relatively’ easy premium tank to get. Even on the DMM version many top tier players have Bernice as their primary tank. She is one of only 4 Awakenable ‘pure’ heavy tanks in the game, including the DMM version. The other 3 being Gellius (platinum), Deine (black), and Maribel (event only). Definitely a must keep and is a direct upgrade from Leeanne.
Another case for A+ tier are Spica, Bashira, and Chydis.
The most common opinion is that Spica is the most important archer in the game. But being a Platinum unit, she is not easy to level. Also acquiring the needed amount of Demon Crystals for her is not an easy task. Spica is also extremely squishy compared to even Daniela, making her placement crucial. Aside from her cons, she does boast the second highest raw damage output of all Archers and has a powerful passive after awakening. Archers being a core class makes having a second Platinum archer quite useful. Chydis is in the same position. Chydis is the best all-around healer in the game currently if you can somehow deal with her HP pool.
Bashira would be S-tier if it were not for her being Platinum. Platinum units are expensive to level and class change for newer players. It will take many weeks of grinding to level up and grind your team to a level capable of unlocking the higher level challenge quests necessary to farm Platinum spirits as well.
Monica is here solely for her passive to boost Demon Crystal drop rates. Demon Crystals is the most important currency in the game. Some of the most powerful units come exclusively from the trading post and with awakening around the corner, so is the Awakening Fairy.
B Tier
Middle of the pack units. They are useful in their own way but are not priorities for leveling. They all have a niche that a team may require to clear specific missions. Some units here have better alternatives that are free or easier to get.
Fedora can make a case for being A tier but I found it hard to rank her higher because for one she is not free and her skill is underwhelming. Even if you do manage to pull her I feel you will get better mileage by leveling Dorca over Fedora. Dorca being silver and free makes her much easier to handle. After maxing Alissa and Iris, one would generally want to try to max Dorca, but if you manage to pull Fedora in the process, then maxing Fedora over Dorca is an option.
Another interesting B tier candidate is Cuterie. Affection is a second way of making your units stronger. In all cases as you progress you will want to increase your unit's affection as well as leveling them. Getting a tiny boost to the rate you get affection items can be helpful. Otherwise Cuterie would be a D-tier unit. You can make a strong case here for Cuterie being lower tiered but I value all the small 'boosts' one can get, no matter how miniscule, as a free player.
C Tier
Below average units that already have better alternatives that are free or easier to get. A curious choice here is Yuyu. She is second most powerful witch in terms of a raw damage but is offset by her abysmal HP pool. In 95 cases out of a 100, you will get better mileage out of Chloris and Calliope over Yuyu. She is not worth the resources to raise at all. A witch’s shorter range makes Yuyu susceptible to direct attacks or indirect splash more often than not making achieving 3-stars on many missions hard. This is from personal experience of using Yuyu extensively on both Nutaku and DMM.
D Tier
Don’t even bother with these units. They are a waste of resources to raise. These units all have better alternatives that are easier to get and level or have better skills, passives, and affection bonus. The entirety of the Samurai class is here. They are simply too expensive to use and their unique ability to attack all units at once is underwhelming at best. A premium platinum Samurai would be ranked higher, but would probably be a C+ tier at best. Too many better options and versatile combinations out there.
