So you are quitting because the only people you play with a jerks? If you have a decent FC they won't care that you don't have TS/Mumble/insertpreferedVOIPhere. Sorry but if your FC is saying this leave them now and find another, if you are PUGing go with your FC, if your FC isn't running endgame find an FC that will run it. You are the one that is refusing to find like minded people and just want to run with jerks.

You could even start asking if anyone is on a server that has less dependency on VOIP and jump servers, you can't even use the friends argument seeing as you are willing to quit the game.
