Lets see what impact cross-realm pvp with Blackrock gonna have on Icecrown.
The vast majority of Blackrock plays human so the faction imbalance in BGs will be further increased.
I can already see BiS geared donor humans from Icecrown fighting in BGs side on side with full rele starter geared humans from Blackrock against fresh 80 hordys who are just getting rdy for PvE.
It gonna be like in 300 but the spartans outnumber the persians.
I for one will definitely multibox on horde side to bring some balance to this fight.
In case of 300 that would be a third war party called "the macedonian phalanx" which roles in perfect sync over the battlefield, killing everything on its way.
