If you can mind control someone on the opposing team, and have the mind control active when they die, they will not be able to ressurect. They are now tagged as your faction and can't find a graveyard. It's possible that the only way to fix this right now is to log out/log in or afk out and get the deserter debuff.

Steps:

1. One faction priest (or possibly an engineer with MC cap) casts MC on opposing faction team member.

2. MC is still active when they die.

3. The dead player is now out of the game for a while.

Right as your team is about to lose, have a priest (or enginner with MC cap) cast MC on the opposing faction. When the other team wins, your MC'd pet will be considered as your team and only receive one point.

Ok here's a way to pvp enable the opposite faction if you want. Click on the person you want to enable, then type /duel. While you're dueling type /concede or /forfeit right before they hit you and they'll be pvp enabled and you can kill them.

1) Play as an engineer
2) Attack a warrior or rouge friend in a large pvp fight.
3) Use Mind control cap on them and hit beastial wing.
4) Beastial wing's effect will stay on them.
5) It will break mind control on them.
6) Easy killings for your friend.
