I'd like them if they where optional traits (like a adept, major, or grand master) not a minor trait, as well as provide buffs that make it worth having the penalty, scrapper is mainly played as a support in wvw, so they will rarely be dealing damage as is, so the"positive" of the trait will go largely unused (not to mention it gimps what the update was suppose to be about has the max barrier you can have is based off you HP)
