I ask this because I have wiped on Malkorok in flex more times than I have wiped elsewhere in the rest of flex combined, maybe 10 wipes total.
His whole mechanics doesnt seem bad, but I have never progressed past flex 3 because of it...
As a tank I dont know if theres much more than I can do than the following:
Let OT get 10-15 stacks and taunt
Mark where smashes happen with /wm command
group up in p2.
Im decently geared for it too, at i535..
