At PAX East an interview mentioned the raiding imbalance at the hardcore level: “The developers are aware of the faction imbalance in hardcore raid guilds and have ideas on how to tackle the problem, but nothing to share quite yet.”
Tbh at this point there is only one solution to the imbalance, which is quickly growing still despite balanced racials, and that is free faction transfers or bulk transfers. (1 cost for all characters. Probably same price as live)
Unless they make Alliance racials ridiculously overpowered, it’s just far too expensive to transfer an entire guild. It’s thousands of dollars (or equivalent wherever you live) to even consider.
So I don’t see how any solution to the raiding population (and the trickle down effect) can work unless it involves drastically reducing the cost to transfer characters.
