Tauren
- Nature resistance (rogue poison hits less and druid roots on you fail often) (19)
- war stomp, can interrupt spells, or get you a small gap when making a run for it
- 5% hp increase, always good.
Troll
- Da voodoo shuffle Decreases the duration of movement impairing effects by 15%. Not sure of how good this is, it's good but meh...
- berserking (attack speed +20%) helps you kill their offense a bit quicker
- 10% more health regen, also 10% regen during combat. Again good but nothing awesome imo
Wouldn't choose troll for a FC
Orc
- Blood fury (AP increase), helps dispatching their offense
- Hardiness reduces stun time by 15%. So HoJ now lasts for 4.25sec. Nothing gamebreaking.
- Expertise with axes increased by 5... yea
Undead
- Will of the Forsaken removes charms, fears, sleeps. So basically just removes a fear effect with a 2min cd. If you're fcing, the fear will break down soon anyways. Dunno, maybe it has its uses.
- Cannibalize When activated, regenerates 7% of total health and mana every 2 seconds for 10 seconds. Kinda quick heal compared to eating. You'll probably have healers to manage that though
- Shadow resistance. Resists fears and some wlock dots. (19)
Goblin
- Rocket Jump. Kinda like hunter disengage but makes you leap you forward
--------------------------------------------------------------------------------------------------------
Human
- Every man for himself. Works like a pvp trinket, and frees up another trinket slot for second agm. So basically reduced trinket cd and 120 more hp compare to other races.
- +5 expertise with swords and maces.
Dwarf
- Stoneform. Increases armor, removes all poison, bleed and disease effects and lasts for 8 seconds. 2min cd. Not sure of how useful this is, but doesn't sound too bad for tanking against melee!
- +5 mace expertise
Gnome
- Escape artist. Removes all movement impairing effects, but not stuns or fears etc. 1,5min cd. Very useful, with a short cooldown as well. Not as good as human racial though IMO.
- Improved arcane resistance. (19) Might resist arcane torrent (?) / polymorph
- dagger expertise +5
Night Elf
- Shadowmeld, stealth in which you cant move or it fades. Pretty much useless.
- Quickness. 2% improved chance for attackers to miss on you. Good if horde has only capped hit rating for 5%
- Improved nature resistance. (19) Roots will fail on you more often and poison makes less damage.
Draenei
- Gift of the Naaru, heals 20% of total health over 15seconds. Can be cast on anyone, 3min cd.
- +1% chance to hit.
- Improved shadow resistance. (19)
Worgen
- 40% movement speed buff, lasts 10 sec. 2min cd. Good for getting away from big groups of enemies. That is, unless you get slowed. Never run away from your healers though!
- crit chance increased by 1%
- shadow and nature resistances increased by 14. Fears, wlock dots, roots, poisons will have reduced effect against you.
Bear in mind some classes have different base attributes than others, and some classes can't do all wsg jumps. Pick the race that suits your playstyle the best!
