There is no character with that name on that realm. Please fix your profile.
Note that this rule isn't just because we don't allow anonymous posting. That is one reason, but it's also so people can more easily help each other in a situation like yours. I wanted to check your armory to see if changing your talents might help tighten up your rotation, but wasn't able to as your profile link is broken.
Thanks very much, that's a lot to chew on.
I've always pretty much played Unholy and I've always found it to be competitive in terms of DPS, especially in terms of AoE where I'm placing much much higher than many other better geared players. That said, I've found that sustained DPS against a single target is where I'm lacking - I very often have to wait for Runes and RP for my abilities when not using UF. I didn't think my haste was terrible, I think I'm sitting around 40% self buffed so perhaps it's just my priority which is lacking.
As I understand, frost is a little more forgiving in terms of GCD's and priority, so I may give it a whirl. I'd miss Gary though...
