Your description matches the AC-X11 very well. And with the AC-X11 you don't get the luxury of being able to cloak or engage very well from range. The AC-X11 is so bad that the DasAnfall stats website has a special achievement for anyone that Auraxes it. Put it this way: I'll admit I don't think the AC-X11 is a "bad" gun. It kills things and sometimes it does so very well. However, it is in all likelihood the highest skill/practice-required primary in the entire game. It's just not easy to use well in any situation, and even in its strongest niche, is easily outgunned by easier to use weaponry wielded by a lower skilled player.
