Guild Wars 2

I’d go with a supply centered setup. Assuming borderlands map with 75 people (Not sure of actual limit)…

Assign a 5 man team to each supply camp. Each supply team would also be responsible for the two objectives adjacent to it (South camp gets SE and SW tower, SE camp gets SE tower and E keep, etc.) Tasks in priority order:
- Kill any enemy dolyaks originating from your camp.
- Capture/defend your camp.
- Zerg assist, 4 people help the zerg when attacking a responsible objective, last man stays to keep eyes on the camp.
- Scouting, one person to each responsible objective – purposes being assessment and harassment – auto-attack the gate to get those white swords up.

That leaves a 45 man roaming zerg which is boring to detail.
The exception to this boring-ness is if the enemy doesn’t properly counter your supply camp domination. It would then likely be safe enough to break the zerg in two to be able to hit multiple non-overlapping objectives at once, best taking advantage of the 4 man zerg assist from supply camps that aren’t being contested. (Say hitting SE tower and W keep, each objective could get 22 zerg+8zerg assist players attacking it)

Edit: Note that this strategy ignores Garrison for purposes of adjacent objectives, as it really isn’t one for any supply camp. I’m okay with this, the enemy can have the garrison on each borderlands, they won’t have any supply reaching them and thus will be able to be easily overtaken by just the roaming zerg.
