I sincerely hope that arena net stays away from unavoidable minor traits that nerf your class. It's not fun.
Daredevil having 600 range steal was bad. Now engineer scrapper, a spec that was meant to be a tanky bruiser has -300 vitality just for equipping the elite spec.
Its just not good design. Period. Please change this... scrappers really got gutted..... stay away from these unavoidable nerf traits please.
