Backstab and piercing mods

[WickedSlayer]

How are these factored in? Basically wondering how each factors in to rogue DPS.

This thread is prompted by my hate of the Nemesis charm..

In my observation of Fascav and Draeos's parses I've decided that backstab with +25 mod is generally 1/3 to 1/2 of their DPS. I'm not sure how much a loss of lets say +5BS mod would affect their dps, or how much +5 piercing would benefit them. They each only use one piercer, but their offhand has a better ratio and all piercers sept for Shanker and above.

archery mod is the same amount?

+25 piercing/backstab skill gives you 67 extra ATK when hitting with piercing weapons/backstab. And it increases your accuracy with them; I can't remember exactly how much off the top of my head but I'm thinking like 2% (absolute, not relative, so 70%->72% and 55%->57%, etc... I think.)

From the parses I've done here and there (and of course I don't have any to show) I thought I saw a bit more than a 2% increase but that is just fuzzy memory
