Awesome, thanks heaps mate that's exactly what I was after. I'm pretty sure I've been clipping my DP and VT pretty badly. I'll also start using my anti-clipping MF macro again, which is basically just "if !casting { cast() } else { return }".
One thing that stood out a lot was casting SW
last; I usually get all my DOTs up as a priority because DOT-uptime = a good thing. I had NO idea it was only going to recieve the contribution of whatever was up when it was cast. I think that's been making a reasonable impact too.
You didn't mention SW : D - is it like Mr Nash said; just slip it in between whenever you can?
I did get to clear ICC10 last night with a mix of guild and friends who were about. When we got to SF they got me to go shadow and work on one side of the adds with a mage. Finally managed to break 4k DPS with basic raid buffs and no flask, and while switching targets back and forth.
Overall not the biggest contribution; I was 2nd last on DPS, and the last guy was an enh shaman who went ele for the adds. Still, I haven't really DPS-ed a raid since AQ40 so I was pretty happy with that.
