Some of the later abilities SOUND better than others but I have no basis on that.Yup, feels to me that thus far rarity =/= power. I think overall Team Composition is more important than how many SS characters you have. Endgame may change my opinion, of course.
Also it takes so long to level without the metal zone, if I can't catch those it'll take ages to get the other abilities anyway. I'm halfway through Ch. 4 and only gone up 1 level on the recruited team. Not even close to the next level either.
ALSO I guess Def vs. Magic def is pretty explanatory, but I don't understand magic attack vs. regular attack. When is your character attacking with one vs the other? or is it always both?
