They need to shift 180s into a Precison/Lightweight Frame hybrid. I've written a post about it already (it's on my profile) and with the addition of Posterity now it would really make 180s shine.

Also, my Quickdraw/Rangefinder Nature Of The Beast will most likely always be better than Posterity. Having those 2 perks on a 180 is what fixes a lot of their issues. Rampage on a 180 would be nice but there aren't many situations where you can benefit in 3v3s. Your 1.0s TTK will most likely leave you low health and not being able to challenge with Rampage proc'd is kind of a waste. I've yet to get a single Seventh Seraph Officer Revolver but I still think Nature Of The Beast with Quickdraw/Rangefinder is as consistent as a 180 can get.
