It does, that's exactly what Lake Wintergrasp currently does and it's going to be a larger part of the expansion style where an entire major city will be controlled by one faction or another. My point is simply that WoW is learning from WAR and soon WoW will have everything WAR has to offer on the PVP side while still maintaining a hugely engrossing PVE side.
Except that's, as I said, expansion content. What I was trying to get across was that, in Warhammer, if you don't RvR (and win), you don't get access to
any of the good PvE stuff. All but two of the major instanced dungeons from level 18 and up are accessed through the capital cities, and if your enemy comes into your capital city, burns it to the ground, kills your king and farms you for gear.... you. don't. get. to. go. If you don't protect your capital city, you don't get any of the good dungeons, you don't get guildhall access, you don't get nothin. Imagine what it would mean to the WoW alliance if, say, Ironforge was the only "alliance city," and if it got sacked and the king killed, all of its amenities and functions simply went away and every dungeon from The Deadmines on up CLOSED to Alliance. It forces you to have a vested interest in RvR. This is meaningful PvP that affects the gaming experience of everybody on the server (whether they want it to or not), not just the optional sideshow tomfoolery WoW perpetrated.
Not only that, but the high level PvE gear also requires you to have extremely high renown rank (RvR exp) as well. We're not talking "pvp set gear" here, we're talking the endgame PvE raided gear. If you don't RvR, you don't get to wear it.
This is not to say WAR is perfect. I can't believe Mythic failed to learn from their previous game, where a crucial design decision (3 fighting factions instead of 2) lent a huge self-balancing paradigm to their game. Now that they only have 2 factions, they are facing a lot of problems with imbalances. This is one of the reasons I have 2 accounts - the fun is always on the losing side. Their scenarios pop faster, and you can always find a zergling swarm of enemies to slaughter, and you can pick a fight any time. When you're on the winning side, it gets kinda boring.
