I currently have 8 warriors and 2 shamans at 60 and am having an incredibly easy time doing rend runs. I can kill rend in 20-25 minutes which is faster than most groups of regular humans can pull off.

Mage heavy groups are definitely significantly easier to manage and are less gear dependant but I’ve found that now that all of my warriors have lionheart helm, devilsaur sets and are almost in full pre raid bis I can just face roll through pretty much every dungeon much faster than a caster group could.

also, I see people are going on about the 2 hander of drak but for speed clearing dungeons earthshaker from MC is the way to go. I’ve got 1 so far but I’d like at least 4 of them to chain aoe stun mobs on every pull.
