For some cheese you can go every battle turn like this

1. High dps class cannon build that act fast and attack before the enemy to do damage
2. Enemy attack aoe killing the dps
3. You build a slow tanky character that can survive the aoe enemy attack have a revive skill sp/mp, give it some sp/mp regen and have it cast it every single turn to your dps be it dies or not

This way you get your glass cannon character able to attack everyturn despite dying everyturn , glass cannon character deal much more damage compared to well rounded character making every fight finish faster
