When I racechanged Versebelg the Troll into Thermalix the Goblin, I debated tossing my engineering, which was then around 250/525. I wound up deciding to sleep on it/forget about it. I’m glad I zoned on the matter, for I recently started leveling it again, and I now have … a FLYING MACHINE. YAY!
This is a vast improvement over my old wind rider (the poor guy needed dental work). It’s also an upgrade over the albino drake I was using. If I had quit engineering, I’d have been that much farther away from a mount held together with duct tape!
