I hate to say it and I do believe that people should be able to play the way they want to but the idea of it seems more toxic and non-beneficial to me. It just leads to ignorance and leaves people more open to being offended then backlashing at others. In a game where you have to rely on your teammates to do their best to assist you with a clear, helping your teammates by doing your best is also helping yourself. Like the OP has stated, doing your part results in faster clear times which results in less mechanics to work with and less overall group work. So if you "play the way I want to" and aren't performing up to par, you aren't helping the group OR yourself.

Sorry if this was off topic but in every thread there always comes to threads which say "let them play how they want to" and whenever I think of it, I don't see any good come from it.
