Scrapper feels awful still. Sure you can maintain quick just fine, but the rotation is tighter. And if you can't safely use a 1000 range leap (seriously wtf) no quickness. Almost fell off a boss platform yesterday because of a phase change. At least fix the 2 second animation lock/make the evade last more than half the cast time.
And it's basically bring throw mine instead of shredder. Same exact setup otherwise, because you want super speed for the damage buff. Only now you have to sacrifice one of your SS skills for clunky throw mine. You're still casting gyros off cd for the fields to combo in, burning even more skills just for one boon.
Want to make scrapper better? Make gyros better! Bulwark is garbage except for the toolbelt Purge is useless since engi has tons of cleanse already, and the poison field toolbelt skill, what is that for?? Reduce the cooldown on blast to make them all pair together better. Oh and bring quickness back to SS. Please.
