Funny story about this. Last night I was a bit, well, imbibed, and rolled a new panda priest on the turtle zone.
I got to the third quest where you have to fight 6 trainees in the temple and as I got the first one to 30% or so pulled in a second with my dot. Thinking I would switch back to the 1st by tab I accidentally pulled in a 3rd. Ok I think, I can handle 3, only to pull in a 4th and then a 5th. Now these guys were all yellow mobs. Why was tab pulling yellow mobs when I had 4 reds punching me in the face?
TLDR - Don’t drink and tab target kids. You’ll end up dying in the panda starting zone like a sad, sad idiot.
