Melee-Cleave Boxing End Game Dungeons

[onsit]

Having some trouble on the more melee damage heavy mobs. Shaman is full pre-raid BiS in mp5 gear to be able to spam lesser + chain heal effectively.

Warriors all have Treant's Bane, and the best pre-raid DPS oriented plate gear (no leather / mail). Along with stam enchants.

DM:N the Ogre packs with more than 4 are completely unrealistic in melee damage. They can easily take down one of the warriors. Especially due to the enrage that the ogres do.

UD:Strat the 5 pack of super elite skeletons right before Baron, is very difficult to get by and almost always requires one of the warriors putting on full Molten Core prot gear just to down them.

UBRS - Rend runs require a second healer, but otherwise runs go pretty well. with just 5 warriors + 2 healers.

Anyone else run into a hard time with these places? Any tips? Seems like I hit a ceiling gear wise unless I can gear out the DPS warriors in Molten Core loot.
