While I'm using my tamer I can't hide without being revealed, no matter where I am in the world, sometimes it's instantly which causes me to not lose aggro and die. I don't know if this is intentional, but it's terrible.
Occasionally, I summon Daemons! When they finish off a mob, and a new one spawns, I reveal when the Daemon gets attacked.
We are slowly working on fixing these but keep reporting any you find. Hopefully I can track all these down for patch 42.
OH! This thread explains one very horrible death to the hordes of mongbats in the Terra Sanctum area in T2A. I had gone there to rescue a friend -- and whie Stuck->Helping out I was somehow revealed and well... slowly mauled to death by mongbats and imps as I was helplessly frozen. WORST, DEATH... ever. haha
