don't invest coupons in anything save up till 20k then go allout during a fuku deal cycle; that way you're getting the latest meta whilst stocking up on power; after that repeat the cycle; don't level up religiously, take it easy. Power comes as you're having fun; if you try to force it, you'll end up hating the game. i'm lvl 76 at 100k ish but that's only because i've been playing for almost 2 years; ya gotta enjoy rather than trying tobe the strongest cuz there'll always be a bigger whale in the sea
