I noticed a bug today
I challenged a guild 3 vs 3. Challenge was accepted. 2 people in my guild showed up, and 4 in the other guild. The game started. It shouldn't have, if I read the rules correctly, nor should there have been 4 in the other guild. After experiencing this, I'm not encouraging my guild to play battlegrounds until this is fixed.

Also, major lag when respawning. I respawn, but takes too long before I can do anything, and instantly get hit.
