Care to tell us where to find those "skilled" horde players in the world? Tanaris = alliance playground, nagrand arena = same, zul drak arena = same, hellfire peninsula = mostly same, but you can see some horde resistance sometimes. Right now there is a group of alliances that farm people that try to enter the wintergrasp. Oh before forgetting, never saw horde groups camping alliance camp on wintergrasp but alliances are almost 7/24 at our camp there. And apart from wpvp, heres the pvp ladder
http://armory.warmane.com/ , only 2 horde teams amongst 50 teams. True that skills>racials but doesnt mean all those people get these bonuses without actual skills.
PS:
http://forum.warmane.com/showthread.php?t=443996 , check the title, its Horde players that qq for being farmed, not the opposite. Warmane had to change tp location to be inside of the fort instead of infront of the gates after a while. And the sec they reverted the change, alliance came back.
