yes. everything dies so quick it dosnt even matter who is tanking/kiting adds
Our tanks picked the strenghs up and we cleaved them down, increasing boss damage. Keeps the dps from having to move as well, which increases dps. Try it.
We have our tanks to tank the Strength as well
I did a part pug, part guild run yesterday just Will of the emperor for those dps who were benched for this week's raid. We had all ranged dps, due to me pulling aggro on my mage, I ended up Tanking the strengths, either blinked or dodged their knockdown attack. So yes totally possible to do without melee.
