Well this is a first

I felt bad about ditching my friend with a bad party, though :')

You should have gotten yourself "accidentally" locked out from the fight so you could have watched the world burn. :P Then perhaps could have continued with the party appreciating you much more...

Of course in group content I try to give people what they want (if it's within my capabilities) so that ended that practice.

I really don't think you have an obligation to start playing badly even when asked.
