btw those stats, 1200 ap 20% crit, ~140 hit rating, those are for combat swords. you need to adjust accordingly for shs and mutilate.
also, your skill/rotation matters a lot too.
most dps spreadsheets will let you manually input gear stats, and while it sucks and can take a while, you can see what your estimated raw dps is and then see what rotation you should use.
just remember to keep SnD up, and to not just dump CPs into SnD when it runs out, as ive found it to be better to use rupture, then use the energy and possible CP returned to put some extra points into SnD.
for SHS spec, you need a lot more hit and ap. 1700~ap and 25% crit minimum with at least 160 rating. you really shouldnt be raiding w/that spec but some people do. you really should go sub/combat to get DW spec and improved SnD otherwise your going to burn all your CPs just trying to keep SnD up.
for mutilate, go 41/20/0. this build should do fine w/the same stats as combat swords. make sure your daggers are up to date, use instant + deadly poison for your choices, try to keep poisons on multiple targets. you get tons of CPs with this build so SnD and Rupture will always be up helping your DPS. if stuff doesnt move around much you should do pretty decently w/this build.
