1. SC plan for a free player is pretty much the same. 35 for box expanion > Saving at least 30 at all given times for collection event units and to a lesser extent farm event units > 30(buy at 60 SC) for second barracks > 30 (buy at 60 SC) for third barracks > After 30 SC feel free to spend on premium summons. However consider saving up to 60 SC once again before rolling 6 times for a premium spotlight you want. There is also a recommendation of spending 5 SC to run pastoral gate with an AW Betty then dumping the earned gold into 2k summons. Though that would be much later for you.

2. Not exactly sure what they are currently, but I know for a fact you could purchase the 7 SC buff and get to the desert missions to farm. Other then that I know you should begin CC around the time you get to Castle Retake. I also recommend keeping your core team close in levels together.

3. If you are refering to Unit level then 50. Though that is after you can sustain the gold cost. Prior to that it is 40-42 depending on rarity. Then you go the rest of the way with platinum+3 fairies.

4. At level 50+ is the only real time you should, but fairies are normally an issue to players. Black and Platinum fairies are normally saved for Platinum Armors. Gold, Silver, Bronze, and Iron fairies are normally used for combinding and event unit into another Event unit. Ex. Azami into Azami. Also Silver fairies are later needed to CC fodder for AW. So be careful with those.

5. Not to much. Each unit just gives 30 more experience. In the desert missions there is a bronze unit that gives that extra 30 regardless of class.

6. Nope. The only time that is the case is for Silver+, and it is level 10 if you don't need to CC it and 30CC20 if you do. The only time you need to CC is when you need it for a SU.

7. No amount of gold will ever be enough... unless you are paying to run for gold, and even then you'll only pay for what you need. With AW now a thing... you run out of gold fast... I had over 2m awhile ago... just a few days earlier I was under 200k which leaves little for leveling and even that will be gone when I get 100 DC again.

8. The gold dump is 2k summons. However, I highly don't recommend doing that unless you need an iron for CC purposes. Just not worth it now with the high cost of AW.

9. Your primarialy used girls. As soon as possible, and saved 200% minimum affection at all times for a new event girl you may or may not use.

10. Your leveling plan is a little off. The Charisma dump should go Pastoral Gate > Tower Overwatch > Dragon Hunting > Fiery Oasis.

11. Your affection Farming is good, but you may want to add Womens Battle 3 if you want to farm black/platinum fairies instead of black/gold

12. Mid-Game Army. You have far to many Archers. Bashira, Daniela, and Spica would be enough. Hayate will serve his purpose until you can get Saki. Bergan shouldn't be needed.

13. At the moment farm until you get Aisha or Nanaly
