You are wrong to compare the WotLK realms to a TBC realm. WotLK changed everything when it comes to faction balance. Every Man for Himself was added which made Humans a viable option to PvP. Prior to that, most PvPers used Undeads and Blood elves when possible. The Alliance had almost no viable PvP perks. This is why you just can't compare the two expansions. When I think of TBC, I never think of the Alliance, albeit I played on a Normal server back in the days, so the faction imbalance wasn't that critical.
