How long before you met your first nasty user?

[Validas]

I met my first nasty user while running Brayflox for the first time in October. I was a new tank, and though I did research I didn't have any experience in that dungeon.

[snip] I haven't played Brayflox's Longstop until this week, and I almost stopped tanking altogether.

Brayflox was also my first bad experience. Nothing extraordinary, just a lot of 'wtf are you doing?!!!?' and 'OMG you suck!!' during my first run ever.
Since then, I wholeheartedly expect every single party I'm in to have at least one overly abusive intolerant member; I'm usually right. Somehow I made it to level 48 where I attempted Aurum Vale...
I did give up tanking that day. I'll probably give up on this game all together pretty soon.
