Player vs. All (PvA), or more commonly known as Free for All, is when you can fight any player of any faction including your own. However it is closer to Group (Party or Raid) Versus All, since group members are considered allies and will not receive damage from you and will receive your heals and buffs.
There are at least four locations where one can participate in PvA:
- Gurubashi Arena located in Stranglethorn Vale
- Arena Floor in Nagrand
- Circle of Blood in Blade's Edge Mountains
- Darkmoon Deathmatch in Darkmoon Island
- Darkbrul Arena in Highmountain
