24 days until Tinker reveal by Blizzard. They have been investing an enormous amount of time from their animation and art teams into creating unique racial animations for the class. They see this as a love letter to the most wildly popular new class request.
Alliance:
Gnomes: Gnomish tech (duh)
Dark Iron Dwarves: Dark iron type tech (Think the drills and the BRD golems)
Draenai: Alien crystal tech (you've seen the golems
Horde:
Goblin: Standard goblin shredder type tech
Mag'har orc: Iron Horde tech (It looks REALLY good).
Blood Elf: Netherstorm blood elf type tech
Mail/intellect class.
Three specs:
Enforcer: Tank. Battlesuit cooldown, with each race having a customized suit. Tank mechanic is built around a shield capacitor, with a focus on building large absorb shields to differentiate from other tanks.
Alchemist: Healer. This spec plays most similar to how MOP Mistweaver played. There's a focus on self-spreading HOTS (and self-spreading DOTS). Some really cool visuals
Engineer: Ranged DPS. I don't want to spoil it, but you guys are going to LOVE it.
All of these archetypes have been explored in WOW. The team has a ton of art direction to pull from and they are really excited about how this class came together.
Edit: 23 days!
