We were learning Maulgar with 2 hunters present. Hunters tank Kriggler, but we still had to MD pull Maulgar to the MT. So I popped MD, distracting shot Maulgar, then pelted Kriggler a couple times. Krigger then ran over and lightning bolt/arcane shocked the MT, who died shortly after. I forgot to click off MD.
Only people in hunter chat ever knew what exactly happened.
In Naxx during Thaddius I remember being grouped with certain people every attempt to pack-taxi them for the phase 2 transition jump because they could never make the jump, ever (most notably, all of our shams).
