Inside abyssea, if you're tanking /mnk is too good to give up over /war imo.

Maybe someone will figure it up, but I find it hard to see 10% DA + berserk beating a possible 4 hit / 5 hit / 6 hit(caladbolg) Especially now with being at haste cap for so long.

Granted I'll probably give /war a try and see how it goes.
