I would like to see an area for PvP that would allow some temporary 1v1, 2v2 and 3v3 opportunities.

I imagine that a hexagonal wall could pop up, similar to the ones that surround the clouds during the final boss in WoD.

It could be that the entire team receives a bonus from points scored inside of the hex when 2, 4, or 6 people are enclosed for 15-25 seconds. During that time, the players are unable to be targeted by other enemies or party members, until the walls come down.

Perhaps for those party members not currently in a hex while it is active, a roaming drone or two outside of the hexes could offer points/buffs if killed.

For those inside of the hexes, there could also be drone inside, offering a buff when killed.
