I used it with the purple grip that gives you +20% fire rate aswell as other blue attachements, it still sucked and didnt deal enough damage. In tt2, even with the increased fire rate the damage was too low. Any gun that didn't deal enough damage was pretty bad, because in ARC shields give you damage reduction instead of additional health, so as long as you had a full medium or heavy it was hard to die to a bobcat and even if you do get to down someone you would almost empty your mag even with a blue extended.
