My only pet peeve with NIN, and this is just me being nitpicky, is they have one ability that requires to be hidden, and even then you have a mudra to discard the hide requirement, because you can't even use Hide in combat, and then they get another mudra to dispel the buff that takes away the hide requirement to generate ninki ....why not just take out the requirement entirely? seems like just button bloat to me /shrug
