Increases chance to hit by 1% for you and all party members within thirty yards
Draenei: Gift of the Naaru
Heals your target over 15 seconds, 1.5 second cast, 3 min cool-down.
This is somewhat wasted on a class that can already heal, but it is the only way a paladin can heal over time. It does not cost any knight gold mana though so it can be useful for helping to heal you while grinding.
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. It is especially good when grouping with other melee characters like rogue and warriors.

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.

Increases shadow resistance by 10

Given the other lackluster racials of dwarfs and humans this probably makes Draenei the best race to play as a paladin if you want to be a member of the
Blood Elf
Mana Tap
When activated reduces the targets mana by 50 (scales with level) and carges you with arcane energy for ten minutes. Instant Cast, thirty second cool down.
