I am still working on my parse project here: http://www.thesteelwarrior.org/forum/sh ... st&t=13652
It is a rough appoximation based on existing parses I have done that Hand of Ro + Sun's Corana decrease a mobs dps by roughly 15%.
I am looking for a way to calucate how much damage would be done during that time frame (whatever the parse duration is) by removing whatever percentage of hits wouldn't have occured due to the mob being partially slowed.
