Thread: Need some advice

Started playing Aigis on Friday, so I missed a lot of the daily missions for this week. I got through the story missions all the way to Armor of the Dead and took a break there. I also spent around $100 on SC and using them for the premium summons. Right now I'm stuck since my units are underleveled and I need some advice on how to build my team so I can do some of the missions in Treacherous Pirate events.

These are my current units so far (a lot of them are missing due to me using them to level up the units in my team):






This is my current build thus far:


So what I want to know is:
1) Is my current team "good" enough to get me through the pirate missions after the second one?
2) Who should I focus on levelling up and CCing at this point? I'm currently farming and gaining exp. from the Tower Overwatch mission.
3) I might be spending another $50 soon, so should I be using the SC on more premium summons or spend them on something else? My goal is to spend as little money as possible.
4) What units should I be using to level up my characters? I've been using iron, silver, and some gold units (probably a bad idea) to level up my units.
5) Maybe this question has already been asked several times, but was CCing my Alissa at around lv. 30 a bad idea?

Thank you in advance.
