I had an unpleasant experience of teaming with him tonight, Deathangel9 (Soldier, lvl 50ish) running a mission with my alt in a 45ish team, where in the end (Was a nice guy until the boss was killed) he ran away with the good loot. When several wanted in on the useful stuff, he said "no", and when I suggested we roll for it he said no thanks, lol, bye (or something similar), and left the team.
Devron19 (Pandoras Wrath) was in the team too, as well as Static.... can't remember Devron19 even got a confirmation from him that he ran away with the good loot, asking something in the form of "Seems like Deathangel9 is running away with what he wants", whereas the answer was "Yup" or something like that. I apologize for not having a picture or a log of this to be able to be more accurate.
We were lucky enough to have one of the generals of his guild in the team, whereof we got a promise of him to kick Deathangel9. It's sad to see selfish people, not aware of how it might affect them in the future. But after all, ignorance is bliss
