the state of BGs is abysmal. Bgs currently award less honor vs Ashran and doing Skirmishes. You have the faction imbalance and fact that one faction blacklists AV/Isle.
The 40vs40 maps def need work as does strand of the ancients and there should be seasonal weather patterns to add some variety to some of the old maps.
Tol barad and wintergrasp are so irrelevant now they might as well be deleted from the game despite being more fun than Ashran they should become Special Bgs that have better rewards for winning than other Bgs and are not part of the Random Battleground roster.
Personally I think random battlegrounds should be eliminated replaced with the return of battle ground weekends and one que roster called " Classic Rotation" Only includes the Original 3 Battlegrounds. Then Another Que map list that includes all the rest with the exceptions of the 40vs40 and TB/WG.
furthermore the honor rewards for queing for a specific battleground might as well be nothing.
