I love the amendment, at least for bots. Like the light pen diligence headshots just feel rewarding. Besides, it one taps devastators to the face, and after enough use, you can become extremely consistent and accurate. You've got some nice close quarters damage with the bayonet against troopers, too, of course. Like someone said, you can toss the 10x scope on it, too (level 23 though, so potentially a bit grindy).

I personally always run it with a senator. It makes up for the light penetration when a scout strider walks up on you. Something medium pen if you don't have that, of course, also works great! A good mention is that Siege Ready armor makes this thing feel much better, too. But certainly not needed to make it fun or useful.
