A harsh deserter buff for not joining the BG (dodging) - 1 hour Duration, Does not decrease while offline, Reduces all stats by 75%.
Reduced respec cost - Or perhaps a new item, purchasable with honor/tokens that allows one to respec? (not sure if this is possible, so likely a reduced cost).
5 player parties maximum for group que - Maximum of 1 5 man group per team in each BG?
If no on the first suggestion, then perhaps a penalty similar to dishonorable kills for dodging, or even a straight reduction in weekly HK count and or honor. Or if really hardcore, both the first suggestion and this one together.
I think changing gear rewards would be too much.
I also don't agree with que from world.
