I usually bring Canas out anyway, since he can double most of the Shamans there.

I play on an emulator so cancelling never comes up. I just save state abuse. XD

Oh God, Kishuna is a pain in the ass. I always bring along the Killing Edge and the lords' personal weapons and just surround the guy with my most accurate and strongest fighters along with their support partners. It takes a LOT of reloading, though.
