how come ppl complaing about no kick option in groups/dungeons/fates when there is 1

i know on a dc'ed player in a instance it works, but i never tried it on a actual connected player in a instance, never had the need too or wanted to be mean to kick someone just to test it lol

Duty finder has a system in place when someone d/cs to kick and replace them. It will ask you if you want to replace them. I think it's made to kick d/ced players after the game has determined they're not connected for a while.
I'm pretty sure that's the only place where the party leader holds that power though. Not 100% on it!
