I was going through my web logs and found something odd, this is a list of keywords people use when they find my site, I guess I should be surprised anyone still comes here but that's beside the point.
I decided to put together a graph in response to a thread on the Rogue forums.
Here you see a rogue without imp evis HITTING an evis for min/max damage vs a rupture from that same rogue vs a rupture from the same rogue on a target with the mangle debuff.
