Here's the problem I have with this whole thread though.
They had a group leader that gets the whole party to change instances multiple times to get away from the idiot kid.
Idiot kid follows.
Things were said.
OP makes his joke.
Group leader suddenly becomes righteous.
OP comes to forum for advice.
Group leader calls herself out as being the group leader.
Group leader then complains about being called out.
Is it just me or is it painfully obvious the only one with a problem was this group leader? I mean, seriously, to call herself out and then talk about how she doesn't appreciate being called out screams issues. SCREAMS, BIG RED FLAG. This tells me that said group leader was the main instigator to begin with. She created the drama then got all self righteous and pretended like she was on the high road the whole time.
I'm willing to bet every item on every toon she had the most to say, and there's the short and simple cause of your problem. Everything that has been said since is complete theory talk that didn't even happen and only came about because of one dramatic person.
