Instead of a Merc Mode, they could let horde teams fight other horde teams in BGs. That'd be a very Horde thing to do. If the pop balance changes they could change it to whichever faction has more queued up starts fighting their own faction.
This article is ridiculous, this is not a problem at all. Horde gets OP racials but has longer queues because of them. How could anyone say that this is unfair?
Horde created this problem and its always been this way. People who pvp a lot want an advantage so they go horde for the OP racials so they can think they are super good and then they spent phase 2 and on of classic griefing as many alliance as they could, telling them to go play retail or quit the game and now crying that alliance did what they said? KEK. I rolled Alliance when classic came out becasue I always played horde back in the day and they had so many advantages. I'm gonna start grinding honor tomorrow just because I read this article and enjoy all my instant queues :)
