Heroic Presence alone makes them one of the best races in the game
Draenei: Gift of the Naaru
Heals your target over 15 seconds, 1.5 second cast, and 3 min cool-down.
A hunter with a heal is a force to be reckoned with knight gold. This is great for cutting your down time while leveling and playing, taming a pet, or while fighting a particularly tough monster. It drops off considerably post 60, but is still an awesome talent.
Heroic Presence: Increases chance to hit by 1% for you and all party members within thirty yards.
This is probably the best racial ability a Draenei has.
Hit is very important to a hunter and it is especially good when grouping with other melee characters like rogue and warriors. Your pet will also get the effect as well which can help considerably with DPSing.
Gem-cutting: Automatic + 5 skill to Gem-cutting. This is like the other crafting racial. They are not terribly useful and have no specific benefits to a particular class.
Shadow Resistance: Increases shadow resistance by 10
As it stands now shadow resistance is only useful in a few select fights in dungeons and very high end instances. It is a nice bonus but do not worry to much about it.
Given the other lackluster racial of dwarfs and Night Elves this probably makes Draenei the best race to play as a hunter if you want to be a member of the Alliance. Heroic Presence alone makes them one of the best races in the game.
