Based off my Ruthless build. Kills are fast, but we end up waiting on spawn timers a little. Mob count is ok, but not epic. Pets are ok desireable. Could probably come up with some spawn-camping, and get away with it, or even design a really good spawn camping Survival Build for 4 summoners. In fact, that might be a "thing" to go after on several maps.
Party: 1 TB Monk, 3 summoners with monk/huntress pets, all at the North stack(s)
SouthWest Stack does not need boosting, it handles itself.
Hint 4: Optional Minions to give cover on defenses
