It might seem unlikely to you, but it's happening. If you don't believe me you're welcome to run a few missions with me in game and you'll see for yourself firsthand. I'm aware of the inherent works. I am aware that scrappers do the best single target melee damage in game (before crits are taken into consideration), however with what I've seen, I can crit in every single encounter on a stalker. You can't do that on a scrapper every single time. In fact on a stalker I can get at least two crits per encounter and on a good fight sometimes three. Three versus none hardly seems fair. Not to even consider the fact that a stalker has a chance to proc fear on every AS it uses.
