Except we don't see even the tiniest bit of what could be called 'technology' anywhere, even in Shattrath. Everything, and I do mean everything, is crystals, gems and jewels. The console you mention? Crystal. The 'machine' he is working on? Crystal. Draenei aerial defense systems? Crystals. Their siege weapons? Crystals.
Why do people insist on Orcs as tinkers? They are, as far as I can tell, one of the most non-technological races in the game, second only to the Tauren. They don't work 'closely' with goblins, at all. Goblins do all their tech stuff. Orcs don't build anything other than the most basic of stuff, like catapults and boats. Humans work much more closely with gnomes than Orcs, yet they're rarely ever mentioned.Dwarves and Orcs would be the best second races, as they work closely with their factions' main tech race.
