I wanted to know why the DPS on my weapons changes seemingly at random. I logged out last night and the DPS on my Vector was 199,196. I logged in today and it's only showing me a DPS of 185,736. I have changed absolutely nothing in my loadout, I merely logged out last night and logged in today. This is getting rather frustrating as it seems to happen constantly. I would very much appreciate an explanation from someone.
