MF casting is what I'm most worried about here. MF might be the filler, but it still does the biggest part of total damage, so you can't afford to mess it up.
1.7s average between MF ticks just unacceptable. With 700 haste I can get 1.3s average between MF ticks, and that's huge relative difference and factor in total damage.
Average MB cast interval is nowhere near as critical, because MB is cast less often and only accounts for a small amout of total damage. The difference between 7.5s and 8s average MB times is relatively not that big.
It's all about finding the balance. With 700 haste I usually get 1.3s MF and 8s MB. I prioritise VT-DP-MB-MF and I'm not overly worried about MB, I cast it if it's ready.
Looking at my dummy parse, the average MF tick is 2692 and MB is about 5075, crits included.
So my MF dps is 2692/1.3s = 2071dps
and MB is 5075/8s = 634dps
so the combined MB+MF dps is 2705dps. (The rest comes from dots naturally, but I'm only compairing MF and MB portions of total dps here)
Let's say I change my priorities and get 1.4s MF and 7.5s MB.
This time MF dps is 2692/1.4s = 1923dps
and MB 5075/7.5s = 677dps
with a total MB+MF dps of 2600dps.
So, I actually did worse the second time, because I sacrificed too much MF for keeping MB off cooldown. The point of this was just to show how much more critical average MF time is to your total dps, you have to get it right. You need to adjust you rotation with the increasing amounts of haste. For example, ppl still do MB-MF3-MF3-MB in their rotations with 600-700 haste, but it just doesn't fit anymore. It worked with 400 haste, but with more haste you'll just end up waiting for the MB cooldown to finish and lose time and dps. With >600haste you are better off casting MB-MF3-MF3-MF2-MB, srews up your average MB times, but you'll do more dps. Real pros will probably foresee the situation and cast MB-MF3-MF2-MF2-MB for maximum dps, I won't, because I know I'll mess it up in a raid anyway.
Next I equip my Abyssal rune to get 784 haste. The rotation feels totally different and better I might add. For some reason I get much less conflicts between MB and dots. Now my MF is 1.27s and MB 7.6s, with the same priorities. But keep in mind that going from 8s MB to 7.6s isn't a big gain in total dps, actually the 1.3s->1.27s MF was a bigger gain. Haste will affect rotation alot, if you adapt with it.
This time MF dps is 2692/1.27s = 2120dps
and MB is 5075/7.6s = 668dps
with a total MB+MF dps of 2788dps
Average MF of 1.7s shows that there is something terribly wrong. You might be cutting MF unintentionally. You can't spam next spell while channeling or you will interrupt it. Are you using Quartz to see latency on your cast bar? Are you using nochanneling macros or not?
