Is it just me, or does the Unholy Presence style as DW/2h Frost not suit your left/right hand either? I know it's only a 33% decrease in the global cooldown, but I've done one dungeon today and my left forearm feels sore and my left fingers are sort of throbbing.
I also feel like I have to spam the buttons non-stop, to not miss out on the reduced cooldown because of latency. With Frost Presence, I'd time my keypresses so that I didn't mash them more than needed, but I can't really do that in Unholy Presence (I find that the animation for the global cooldown sometimes bugs out and doesn't display the reduction).
Now, EJ mentions that Unholy Presence is a 500 dps increase over a Mastery heavy Frost Presence build in tier 11 gear. That's quite a bit, obviously, but I'm wondering if a Frost Presence build wouldn't amount to higher DPS if you're prone to "forgetting" or missing attacks since you'd not be utilizing the GCD reduction.
Personally, I've found that I do about the same amount of damage in Unholy Presence as in Frost Presence, but my Death Knight is only level 83 right now. Not having arthritis at the age of 25 might be worth losing 500 DPS over, though.
Frost Knights, any thoughts on the switch to Unholy Presence? What do you roll with?
