Yeah, but I feel it would be a missed opportunity when on top of that the class could have Draenei or Blood Elf-style crystal mechs, Dwarven style tech themed after Titans, Harvest Golem styled things for humans, Forsaken-themed heavy metal suits, Iron Horde style tech separate from mainstream goblin ones, and other stuff like that. Granted with all the races out there it would be a quite massive undertaking tho. And things like Darkspear Troll, Night Elf or Tauren mechs could end up looking a bit silly as well.
Anyway 11.0 isn't going to have Tinkers so it's a discussion more for a potential 12.0 thread anyway.
