Although there are a great number of Shamans floating around in WoW there are certainly more Mages then one initially expects on the horde side as proven by BG. There are a number of rogues for the Alliance but all in all at least on my server the classes are pretty evenly mixed for Alliance. As far as Blizzard need ing to swing the nerf bat on any clas I think it's ridiculous. There are ways to beat every other class in the game in PvP if you take the time to learn what works and pay attention to what the other player does. Watch for a warrior to change stance, a hunter to lay traps, interrupt a mage, druid or priest from casting, fear a palladin, dot a rogue to keep them from vanishing, break down the totems of a Shaman, if a hunter hits really hard at range then get within their melee range; if opposite then stay at range and hit with everything you have when they die the pet goes poof, for a warlock pay attention to what pet they have out. It's not that hard to beat another class in WoW you just need to know the best way to fight each one. The best way to do it though is to actually work as a team which the game was designed to do. The Alliance would win more often if they worked together instead of whining abouut which class is more over powered and not taking the time to figure out all the nice tactics that you already have to go up against every class out there. The game is meant to be a challenge for the single player, that's why you have guilds, that's why you have raids. Take the time to talk to someone who has a different character then you and they'll tell you what the weakness for thier class is. Even Shamen say that their toons suck and some other class needs to get nerfed because they are overpowered. A little bit of patience can go a long way in this game.
