iirc around that level Legendary Pixie can be good at protecting front and rear if she can clone and get to the back in time. If she works straight up that's 4 slots for dps. If the timing isn't right Crimson or Kraken can alter things, or Horse can just buy some startup time. Ideally the dps toons are middle of the pack. Magic:Cyclops+Yeti, Theif. Phys: Bard, Hydra, Plague.
The meta might still be completely different on your server but hopefully these ideas are food for thought. Good luck!
