User blog comment:ZakeIsALobster/Assisstance Needed for Making a Squad/@comment-23870891-20150809030925

Your current squad is actually very good. However, my one piece of advice would be to replace Vanberk with Quaid (cost permitting). Once you get further into the game you can make some greater changes. Given what you have here my thoughts on an ideal 7 star squad would be: Zenia leader (bb spam, spark damage, and bb damage), Quiad (4 elemental buff), Aaron (mitigation and def up buff), Medina (lots of bb fill), Colt (crit and more bb fill).

As for your units, you have a lot of good ones, but many meh:

Great: Aaron, Zenia, Quiad, Colt, Yuura, Oguro, Medina

Potential (as in not currently, but will get 7*): Farlon, Aurelia, Farvnil

Good: Toutetsu, Regrard, Diana, Tazer

Meh: Everything else

Hope you find this helpful (this is all just my opinion, but I am about level 269 on both global and japan).
