No I think the OP means when people say "It's my sub! I play how I want!" then the OP will reply with "Oh...so do you mind if I tank this entire dungeon in Sword Oath while you tank? Meanwhile, I will use Cover whenever possible and Clemency the party? Because that sounds like A LOT OF FUN to me."

Often when you try to give helpful advice people get defensive. I mean you are basically saying "you can do it better like this!" and I guess some people don't like that. Often "I don't care! I pay i play how I want!" is a standard answer to feedback/criticism.
