It suffers the same fate almost every Pulse Rifle does... the stability kills it.
I think Pulse Rifles should have a different stat. Pulse Accuracy, basically.
Pulse Rifles should inherently be 100% stable, as in your cursor shouldn't move at all when fired, or if it does, very very minimally.
Now, the Pulse Accuracy should impact how accurate the 2nd and 3rd bullets are compared to the first. So imagine a Pulse rifle with 0% Pulse Accuracy, the first bullet hits the cross hair mark dead on, but bullet 2 and 3 are off by a full degree. Where a 100% Pulse Accuracy leave bullet 2 and 3 dead on the cross hair mark to accompany number 1.
Basically, I want something closer to the BR in Halo 2/3. The only Pulse Rifle I like is the Stangers, and it was okay for what it was, but only because it had perfect stability. I've used Red Death, and it's okay, but it's slow rate of fire combined with it's not quite perfect stability make it lackluster.
Long story short, Pulse rifles don't seem to offer anything unique about them. They don't have a specific range they are good at, and they don't seem to accommodate any type of specific play styles.
