If people have the attitude of "You don't pay my sub, You can't tell me how to play my job!" They're entitled to think that, but the second they step into harder content (Savage, EX, ULT.) That attitude needs to go out the window. Especially in learning parties. Though it doesn't happen often I've seen More than a few people who seem to think that other people should carry them, and they should be immune from criticism for their performance which is causing wipes.

People overall just need to accept that criticism and constructive feedback =/= a personal attack.
