First of all, pardon my bad english if mistakes may happen.
Trifke is the name.
I've created a group for a tribute run. We were starting to kill the first boss to get the key then reset, Trifke asked me for lead to reset the instance but I did told him I had the macro ready too, then we did. I finally gave him the lead when we started the instance, then he started telling the priest when to sooth/MC while priest was full T2 (Trifke was not even pre-BiS...).
Then he started to tell anyone how to do their job. Three of us started to answer him that we know our jobs, when to use a key, when to sooth a mob etc... Since he couldn't have the last word, he said "Ok I'm afk it will be fun" or something like that, just when we started to pull a pack. We did die obviously, I used Brez on priest so we can get ress'ed. Since he did start to act like a retard, we did ask him to give the lead to anyone else but him, because we didn't want to get owned by a bad guy who could be a ninja too.
As you could guess, he refused to, and he started to use bad words to everyone in the group. He pulled Gordok and we wiped again. Then we did spend all 5 like 15min front of Gordok, argueing to get the lead on anyone else (pug grp). We did not want to kick him, just to get the instance done without a ninja, he was the tank.
15 whole minutes.... and he did finally keep the lead, forcing us 4 to accept the risk of being ninja'ed.
I just wanted to be sure, since maybe the staff won't do a thing about this, to get the community who read forums informed about this guy : Trifke. He's a really toxic player, do not ever group with him.
