Replying based on ninja experience, but with those stats, you'd be doing better damage with mephisto (tho -30% hp does suck). Ira is still good for damage, but boo beats it now plus the added resistance. Monty is great still, but raton is kinda dead now. You'd be doing more damage with vida/melee+15% to element xtal. As for spec, the mq 2s spec should work.
