Guild Wars 2

How to:

Die in match, go to spectate before revive.

Reenter match on same team. You are a corpse, you will not be able to revive/wp.

Correction, this also happens if you jump to spectate while dead and join the other team. Either way, you are perma dead.

Another update: while perma dead if you choose to Volunteer to join the undermanned team, you are sent to their WP as revived.
