User blog:Yuuran/Would you kindly?

So I'm in a bit of a situation with my mitigators. I'm unsure to use Dolk or Krantz(Both 7* BTW) on my team. I've noticed that they both kinda do the same thing in terms of BB. Krantz removes status ailments and provides a 50% damage reduction debuff, and he also adds Light/Dark element to a units attack for 3 turns(Correct me if I'm wrong). Dolk does the same, but instead of adding elements to attack, He provides a 3 turn DEF buff(I'm refferi to BB and not SBB/UBB for this because I currently haven't maced out Dolk). All I wish to know which would be better suited for Trials, Raids, GGC, etc...
