I'm considering a race change to an actual DPS race since I've now stopped tanking but I'm very undecided right now with all the inaccurate information flying around so figured I'd ask before wasting my money on picking the wrong race.
I've done some napkin maths and the Rocket Barrage just doesn't like that hot to me adding a "whopping" 55k damage over a 16 minute fight? Recent reports say that Goblin is slightly better than Orc but I just don't see how with how little damage Rocket Barrage does (~6k with all procs) how it wins out over Orc...
Is there just stuff that I'm missing? Does the Orc pet racial not work for Ghouls as Frost or do they still get benefit?
CortDK has one of the most recent sims (found here) regarding Goblin and Orc viability as Frost. Both races are equally viable, but Goblin pulls ahead by a few hundred DPS due to Rocket Barrage, the ability to Rocket Jump into a fight just a few seconds early, and the Haste racial.
To answer your question, Orc is superior to Goblin when rolling Unholy, because the Orc racial affects permanent pets, which the Unholy ghoul is, however, the Orc racial does not extend to temporary pets such as Frost ghouls.
