It's definitely a strange feeling as while playing today Horde won most every single game. Horde was absolutely dominating.  Gained about 3300 Arathi Basin reputatoin points. It makes sense in a way I guess. On some other servers I've played (non red servers) Horde dominates the pvp. 

The rate of rep gain should increase for players after particular battleground themed equipment significantly. 

I didn't find that whole pvp with the Silithus and Plaguelands zones too entertaining, however.
