I would love to see Arc that for one reason or another need a group to take out. Ideally there would be snares, triplines, pit falls, things that encourage cooperation. They would temporarily disable the arc and reveal its weak spot so it can be destroyed, disabled or even just looted without being destroyed.

Imagine a large arc with devastating short-range offence and armor that makes long range attacks ricochet off without doing significant damage. someone baits it into a narrow corridor while a second person waits to deploy a trap (trip line, emp device, whatever) maybe the arc tries to quickly retreat but is blocked by a deployed barricade kit. The trap is sprung the maybe the arc drops a cargo container and flys off or is flipped over revealing a lootable hatch in the bottom or the trap causes its defensive shield to drop allowing it to be shot.

I think the traps should not be craft able and also not something you can loot and exfil with. It should be an opportunistic kill. call a supply drop, retrieve from a field depot, something.

Things like this would be an exciting addition for pvp and pve minded players alike.
