DERP.
Ontopic: Yes, happened several times. It even happened lately actually, I killed a Rogue and a Resto Druid 2v1 after which the Rogue made a level 1 char and suddenly we had this intelligent conversation:
He: OMG U ONLY WIN BCUZ THORNS....
Me: Thorns was on CD, I didn't use it...
He: THORNS IS OP U ONLY WIN BCUZ THAT
Me: ...I said I didn't even use it, but yea it's OP. Imagine if I DID use it.
He: NO ITS OP AND U ONLY WON BCUZ THAT
Me: .....
He: NEXT TIME NO USE THORNS LETS SEE THEN.
--^ basically a copy of our "conversation". He used these exact words.
Sometimes I really don't get what's wrong with people. I mean, QQing is one thing, QQing about something that's OP is a second, but QQing about something that didn't happen, now that makes you one hell of an awesome troll.
