Blood Asp and Fafnir feel way too cheap for the devastating firepower they bring to the table.
IMO they obsoleted just about every other assault, because holy crap they're good :V
I'd definitely take a second look at the Atlas line, because with the exception of the E, they all look extremely anemic at this point. The Blood Asp and Fafnir definitely raised the bar for firepower, and unless something changes (their cost, other Assaults getting more powerful, or a nerf) they will be the go-to assaults for 95% of players.
Pulse lasers are wicked now, a much welcomed change. I was actually thinking the other day about how Pulses and Beams were quite similar; now with their faster fire rate and shorter firing time they can operate more like X-Pulse - they can hit critical/consistent parts that only have small windows to be shot.
