Priests had unique racial abilities in Vanilla. If you're planning on playing a Priest, your desirability at endgame begins at level 1.
Paid race changes weren't a thing in Vanilla and debuted in Wrath. Don't make the mistake I did when I first began playing WoW and made my Priest a Human, as they were much worse than Dwarf at endgame since they lacked an important tank buff: Fear Ward.
Anyway, take these into account when making your priest.
Human:
- Feedback: The priest becomes surrounded with anti-magic energy. Any successful spell cast against the priest will burn 18 of the attacker's Mana, causing 1 Shadow damage for each point of Mana burned. Lasts 15 sec.
This is a useless ability and had very niche use. Remember, Arenas weren't a thing in Vanilla.
- Desperate Prayer: Instantly heals the caster for 134 to 170. 10 minute cooldown
Dwarf:
- Fear Ward: Wards the friendly target against Fear. The next Fear effect used against the target will fail, using up the ward. Lasts 3 min.
Here it is, the one extremely aggravating racial ability only available to the Dwarf. In fact, Dwarf Priests were so sought out for BWL that max-level Dwarf Priests would be PAID to hop guilds. It wasn't uncommon for level 60 Dwarf Priest players to get multiple whispers a week with offers of an immediate raid spot for progression. Back in Vanilla, fear was a big deal. When a tank was feared, all aggro would be dropped and the boss would immediately begin attacking the next in line with threat - usually the healer or rogue if my memory serves me right.
- Chastise:: Chastise the target, causing 47 to 53 Holy damage and Incapacitates them for up to 2 sec. Any damage caused will awaken the target. Only works against Humanoids. This spell causes very low threat.
This was another niche interrupt ability. It had a few good uses, though if you had your priest assigned to kicks you weren't doing it right... (Shadow Priest you say? HA! Don't make us laugh)
- Desperate Prayer: Instantly heals the caster for 134 to 170. 10 minute cooldown
Night Elf:
Considered the absolute worst Priest race in the game.
- Elune's Grace: Reduces the chance you'll be hit by melee and ranged attacks by 20% for 15 sec. 3 minute cooldown
- Starshards: Rains starshards down on the enemy target's head, causing 60 Arcane damage over 15 sec. 30 seconds cooldown.
Nothing much to add here. Both abilities were nonsensical for raiding and Elune's Grace was only used for flag running in Warsong Gulch. I'd appreciate testimonials from any Vanilla NE Priests though! You guys had it pretty rough..
Undead:
Considered the second worst Priest race, and by far the worst of the two Horde Priests.
- Touch of Weakness: The next melee attack against the caster will cause 8 Shadow damage and reduce the damage caused by the attacker by 2 for 2 min.
It was a niche PvP ability only useful against Rogues.
- Devouring Plague: Afflicts the target with a disease that causes 152 Shadow damage over 24 seconds. Damage caused by the Devouring Plague heals the caster.
Another niche PvP ability.
Troll:
- Hex of Weakness: Weakens the target enemy, reducing damage caused by 2 and reduces effectiveness of healing spells by 20% for 2 minutes.
Yep. The only other Mortal Strike effect in Vanilla came from Troll Priests. Needless to say, huge PvP boon
- Shadowguard: The caster is surrounded by shadows. When a spell, melee or ranged attack hits the caster, the attacker will be struck for 20 Shadow damage. Attackers can only be damaged once every few seconds. This damage causes no threat. 3 charges. Lasts 10 min.
Another niche in PvP, but wasn't hugely powerful.
