Crossfaction bg will be the future due to 90% hord population growing or some mercenary npc like how Warlord of dreanor had when there was no hord for bg or just make it pve realm so alliance will actualy level up instead of getting ganked and rerolling
No way, if you rolled horde you should also get the part of the bigger faction which is VERY long queue times, thats the downside to being on the most popular faction, if you want faster bg queues use the free faction change to alliance.
