I went Alliance because I wanted shorter queues for everything. Horde queues are +15 to 20 minutes and it's ridiculous on US realms. I'm playing an Alliance warrior on Bleeding Hollow at the moment. It's fun because BH is one of the most popular wpvp servers next to Emerald Dream. It's about 75-25 Horde dominated but both sides are incredibly active and Alliance dominates and holds its own. I may move to ED because the servers there are more balanced for wpvp.
Really depends on the realm. The one Grievance was on had a massive horde playerbase.
Only plays Magic DPS Classes, Healers and Machinist/Engineers.
