So the problem was we where 2 tanks in the arena a paladin and me (warrior).
The paladin picked up the Dark Rune Evokers and I was on Dark Rune Champion.
With the first 2-3 champion jumping in there was no problem but after that i kept loosing them and they was like an "arrow" in the group in middle of the room.
I use macro "/tar Dark Rune Champion " but if there are like 3-4 of them in the room it took to much time to select the one which is in the raid and he kill a healer or a DPS and wipe the raid.
So what I'm asking is for some useful tricks, macros from people who did this encounter and how had my task and how did they manged it.
