I'm torn at what I should do. I have a brand new account so I want to level one of the new races but not sure what. I have no 80s so it's all fresh.
It depends on what you're looking for in a new character. Starting Zone quests? Racial Powers? Racial Mounts?
Starting Zones-
I ran through them both now and I enjoyed the Goblin starting zone more. They have some quests where you get a loaner vehicle to run around the city. Thing is you can run over pedestrians and they give you crap. It was so funny that for 15 minutes I ran all around the city running people over.
The Worgen area wasn't designed well. I died due to quick respawn rates on an elite quest monster and had to spend the next 10 minutes running back to my corpse. Don't get me wrong a lot of the quests are alright but they need more graveyards.
Racial Powers-
Again I think the goblins have it better. Always get best deals with vendors, 1% haste bonus, +15 Alchemy, Rocket Jump, Rocket Barrage launches a rocket at enemies(shares cd with the jump), and Access to your Bank every 30 minutes for a minute.
Worgen get Nature and Shadow resistance, 1% crit boost, +15 Skinning and almost instant Skinning, Darkflight (like a Rogue's sprint), and transform inbetween Human/Worgen.
Mounts- Worgens get Running Wild spell which lets you run as fast as mounted people. Goblins get a motorized Tricycle. Only Worgens can learn the Running Wild spell. I think the spell would win because in PvP situations it can be hard to tell whether they are mounted or not without targeting.
