So using a classes own tool kit to help themselves is a disadvantage? By that logic Bards and Mach shouldn\\'t give themselves TP, Paladins shouldnt Clemency themselves, etc. Its part of the kit and perfectly fine to use on yourself. And like I said AST also have lower MP costs across the board. I have died in A3S on AST and cleared it only getting Ballad when I got ressed.

CO like I said has a ton on of spots to be useful on A3S. You disable CAscade put the bubble up and the regen will take care of the rest for free throw in another heal if your people too to much from it. You can put it up for every Mortal Rev on A4S. You can use all the time in A2S as only the jaggaed dolls cleave. And you can use it every jump in A1S.
