Good number of mobs, good number of chests, good pets, build is solid.
North Both Buff beam is 6 DU long to be sure your seedbombs get LOS at the NE crystal.
Party: 1 TB monk (on SWest build) and 3 summoners with guardian pets (monk/huntress), 2 on North build, 1 on SWest build.
Hint 4: Optional minion placements in case you're getting heat at rush time, I haven't used them yet, but did take quite a few hits on the SWest Stack, so some minions would help.
If running 6 players (2 accounts), I would add a TB monk to North stack and 1 more summoner (monk/huntress) on South stack, this would maximize all boosts Should cook pretty hot.
