Well I realy understand you, if you still need the eq it's realy anoying to loose again and again and again, but as soon as you have a good Equipment it's way more fun to fight against each other instead of just killing NPC's..
Like it was back in the beginning of the alterac valley where you used to play for hours on the same battleground, getting the riders and the flying units.. *what a great time :D*
But a sign to explain the bg's wouldn't be such a bad idea anyways.
