Out of the six races available to WoW monks, all will inevitably make for a good PVP experience if you're having fun, but each of the races abilities can provide a useful or almost useless edge in the battleground or arena.
Here's a quick look at the races and how their abilities affect the PVP monk.
- Pandaren: Pandarens have a little usefulness in PVP, and that comes primarily from two of their racials: Bouncy and Quaking Palm.
The former can help mitigate falling damage which can rarely be fatal, so it's better to have it that not, and Quaking Palm is another stun or interrupt in your arsenal so it's very useful.
Epicurean will help you have those nice food buffs stay with you for longer which is good to have. - Blood elf: Arcane Resistance will provide you with a slight reduction in damage from some of the abilities of Arcane Mages, Hunters and Druids.
The difference in damage is small, but there is a slim chance it could help you in a difficult situation.
Arcane Torrent is a small AOE silence that restores some rage, energy or mana and can act as a backup interrupt behind the monk's primary one.
It will be useful from time to time, but not hugely. - Forsaken: The small amount of shadow resistance, like the resistances other races possess, is rarely noticeable and highly situational.
It a plus to have it, but not a big one.
Will of the Forsaken is a mini-trinket on a two minute cooldown that only removes fear, charm and sleep.
It definitely has it uses against Priests, and to a lesser extent, Warriors, so it will be of use from time to time.
Perhaps moreso in an arena than a battleground.
Cannibalism is close to useless in PVP because your enemies will rarely give you a chance to use it in the midst of combat and if they're not around you won't need it anyway.
On the other hand, Touch of the Grave has immense potential in any PVP setting, but will likely see some nerfing to bring it in line with the others.
Even so, it could be quite helpful in the heat of battle, adding to both survival and sustained DPS. - Orc: Blood Fury and Hardiness are the only useful PVP traits for Orcs.
Blood Fury will provide you with a short term damage increase, and Hardiness will allow you to break stuns slightly more quickly than others.
Six second stuns aren't uncommon in PVP and can seem like an eternity when you're getting beat down, so shaving off a second can be a life saver. - Tauren: Like a few other races, Taurens have a resistance.
In their case it's Nature which is also minorly useful.
The extra health provided by Endurance is never something you should ignore even if it's only a small amount.
Having said that, a level 85 in good PVP gear could have over 140k hit points and 5% more would add on 7k.
Not too shabby at all.
War stomp is a nice AOE stun that you can use to interrupt, beatdown or flee a little.
It's also extra annoying in crowds and you can't put a price on annoying your enemies. - Troll: Three troll racials are of some use in PVP, four if you count the extra damage on beasts which only comes into play against Hunter pets, but I'll ignore it here.
Da Voodoo Shuffle knocks a little time off of snares and they are extremely plentiful in PVP, especially battlegrounds.
It may save your hide more than once or it may not.
Worth having though.
Regeneration is something you may not notice in combat since players can put out an obscene amount of damage.
Whether this is addressed in Mists with larger health pools at the end game is unknown, so its usefulness is open for debate.
Berserking is a nice ability you can macro into your burst damage cooldowns for a little extra oomph.
It can be useful at times, but given the amount of stuns and slows you may find it wasted from time to time.
In my opinion it's better to have an extra stun of your own or something passive.
However, if it gets nerfed into the ground, then I think Taurens or perhaps Orcs will be your best bet.
