I had this idea and thought I'd share.

This would be a new PvP mode that has a format similar to PvE dungeons. There would be trash mobs to kill, bosses, and treasure chests to open just like normal, the major difference would be that there is more than one team and each team has a different starting point in the dungeon and a different pathway through the dungeon, but the paths allow for the teams to intercept each other at various points in the dungeon such as boss rooms.

Boss rooms wouldn't have lock outs like PvE dungeons so if one team gets there before the other, the slower team can attempt to kill the one engaged with the boss and steal the kill.

Killing bosses would give points similar to killing the interceptor nodes in frontline and also drop treasure chests which only the team who killed the boss can open.

Treasure chests would contain buffs that drop to a random player on the team that opened them or reward a small amount of points to the team that opened them.

Whoever has the most points at the end of the dungeon when the final boss is killed is declared the winner.
