Same plugin by Droidz with Alterac Valley added to blacklisted battlegrounds.
Why adding Alterac Valley, you may ask.
1) Some servers are filled with multiboxers/premades camping ressing points, so in my opinion it's better to leave the bg and taking deserter rather than getting farmed over and over again, giving free reinforcements to enemy team and looking very bottish, specially when people ask to stop resurrecting and you keep doing it.
2) Using the "free mode" the character goes into caves, mines, goes back to starter point, climbs towers then fall down and loop forever, and similar stuff..all things that a normal player would never do.
3) It's a long battleground anyway, that not always leads to a win (or let's say it worths the time consumed), so again, better to leave bg and hope the next one is faster and more productive.
