Depends also when you're playing. Most of the time yes Alliance is winning, but if you play at night then Horde is winning as alliance sleeps then and most american people come online.
Its no longer pvp server, If you guys are seeking quality pvp you are to look elsewhere. With the recent changes, arena/bg merges they made a mistake, no one is addmiting it. The blinding example is the Lord 2v2 (3v3) ladder which used to have different comps and some interesting challinge. Go to the 2v2 ladder now and tell me how many teams from Lord you see? Go no check it... no need to say more.
