In an equally geared battle, Horde have a slight advantage due to certain racial abilities.
When said Horde are geared with rank 8+ PVP gear (or in the case of AD's A-teams, 11+) against people with greens or standard UBRS/Strat/Scholo raid blues, it's a slaughter.
I found this on the Official WoW forums:
I wrote a very long, angry rant in response to that post that you pasted. I have decided to spare you all my ramblings, and I will just say this:
That guy has no idea wtf he is talking about, and is wrong on almost every point.
Paladins are far superior to shamans in AB and AV because of their ability to singlehandedly defend a flag for at least 20+ seconds against any number of attackers. This gives time for the rezzers to rezz and backup to arrive. Paladins are also starting to learn (finally) that they are much more suited to defensive roles than to offense, and they actually heal their team. They are very good at it because you can't stop them from doing it. Shamans rarely heal their team, preferring instead to cast shocks and chain lightning. They are very ineffective healers, especially when you take into account that few shamans are specced for healing.
In AV, you get really crappy honor. The only reason to go is to raise your rep so you can get the exalted rewards. The exalted rewards, however, are mostly weapons. Thus, you get very few priests and druids (both sides), because there isn't much from AV that is worth their time. Shamans and Paladins, however, all want an unstoppable force, and you get tons of each class. Thus, horde side has very few healers (since shamans dont heal, and suck at it if they do), while the alliance has lots of paladins who heal everyone. This gives them a big advantage.
Shamans might be better in WSG, but no one does WSG except on the double honor holidays. AV and AB are run nonstop, every day.
Layout of the battlegrounds is pretty much even. There is an exploit that allows alliance players to cap our AV towers through the wall, without aggroing the commander on the top floor, but it is a minor thing. Most of the things that guy said are complete fiction.
Anyways, if you're thinking of leveling a new character on a pvp server, I think you should be warned:
I have two level 60 horde characters on a server where horde is the minority, and I have multiple alts over 40. I think I am as qualified as someone can be when I say this: it fucking sucks. If you're thinking "cool, I get to fight against players I encounter as I adventure, and we can battle over quest resources or just for the sheer fun of it!", then I have news for you: You're a year too late, you should have played pvp at release. That's how it used to be, not any more. Today, leveling up on a pvp server means "cool, I get to be ganked by level 60 night elf rogues constantly, and then corpse-camped by them because they have never been laid and need to take out their aggression. Also, if I do manage to find someone my level and have a fair fight with them, if I win, they will get pussyhurt and call in everyone in the zone to camp my corpse because they have never been laid, and need to take out their aggression." If you think I'm exaggerating, ask Rasberry. I leveled up my second level 60 with her, and she's seen what it's like. Once you're 60, things aren't that much better. You don't have to deal with the lone level 60 social outcasts who roam around looking for easy prey, because most of them suck and won't engage in a fight they might actually lose. That's a plus. However, now you have to deal with level 60's who are trying to kill the same thing that you are.
No matter what you are trying to farm, chances are good that sooner or later someone else will come along from the other faction, and they will want to farm it too. If it's 1vs1, oftentimes both parties will leave each other in peace, because if you fight you'll just take turns killing each other as you're fighting mobs and no one gets anything done. However, if it is 2vs1, you can rest assured that they will kill you, because they can do so at absolutely no risk to themselves and they get honor for it. If someone is riding by and sees you fighting a mob, they will kill you because they get honor for it. As I was writing this I was fighting some scorpid in silithus and a 60 rogue and warrior rode by me, stopped, rode back, dismounted and killed me, then left. This happens a lot, and all you can really do is try to find the most out of the way place possible to minimize it. Or, drag your guildies along to farm with you.
Really, the only good thing about being on a PvP server is that if you enjoy battlegrounds (which I do, very much), you can get into them easily and quickly. I absolutely hate outdoor PvP. It stopped being fun a long time ago, when people abandoned sportsmanship and instead simply want HK's and to be assholes.
