Maybe it was just because I had an amazing comb, but I found the fight insanely easy with 2 mage, archer and fighter. Although I can't imagine any halfway sensible comb to struggle.
The ones that were close would simply be ported away on top of other ones and lit on fire, while the others that couldn't be teleported were hard cc'd. With blood lying around everyone, a single lightning bolt will stun so many, and their near non-existent shields meant cc all day long.
