Challenge modes?

[Kruschpakx4]

I did a couple of tries half a year ago, mechanics are doable for quad boxer + tank, dps and healing wise enh shamans do fine so I guess with a lot of patience and endless wiping one could do it in 1-2 month. The difficulty is finding a tank who is willing to go through this , ofc you can 5 box them too, but thats equivalent to go for rank one in every arena bracket

I will give those CM's a shot in summer
