I took the time to google this player and come here because he is an incredibly toxic member of the community; I reported him and want to make sure this gets visibility. Me and three others formed a shout group on Leviathan and joined queue for AK. We were paired with this individual after a 45 minute wait.
We started off fine, even if Ultimax was a bit hard to understand. He mentioned me missing sleeps as a BLM, and I was caught off guard since I rarely sleep trash on level 1, and instead only sleep houndlights. So, given the propensity for mobs to summon adds, I led slept groups to keep the void summoning from acting, and also the aoe sleep worked more effectively. Ultimax responded by saying tank was supposed to pull, and let the mobs wake and wipe the group. Obviously emotions ran high, and one of my teammates was very upset. The other teammate and myself apologized, and offered to let him continue the dungeon. He did not, and instead went afk.
