What's your definition of a Tinker?
Where exactly can you buy pocket factories in WoW? Further, where can you buy a mech with a factory installed within it? Wouldn't a more likely scenario be that the Tinker just built it himself, since Pocket Factory and mechs are two of the original Tinker abilities from WC3?Can just be a Mech Pilot because all you are doing is one item that producing everything ... that thing you are describing doesn't have to be a Tinker. Yes, he could have made it ... but he could have bought it or was given it.
