Please Blizz remove the deserter debuff from leaving bot filled bg's. In arena's when your partner has died and the opponents are full hp, the smart thing to do is leave. You except the loss and queue again. You shouldn't get a deserter debuff cause you realise that its not possible to win.
Imagine the scenario : warsong gulch, you're two flag caps behind, ur team is being honor farmed at the grave yard and there's 15 mins left on the clock. Noone listens to your pleas to stop rez'ing beause well most of them are bots.
You choices are sit for 15 mins until the end of the bg or leave and get deserter for 15 mins, I want to play and have limited time to. It's unfair from my point of view that you can't just leave and queue into something better.
