Here is a talent build I cooked up that tries to spam IT as much as possible.
Talent Calculator - World of Warcraft
It basically uses both DRM and Blood of the North to convert Blood and Unholy runes to Death Runes; Frost runes get converted too, but we don't really care. If Blood Tap is off of CD, we can use the Death Rune for yet another IT. Since this spec uses DRM, it should play a bit more like a typical Blood rotation except we spam IT instead of HS, and use OB to build up Death runes. Yes, this build probably has lower DPS, but I really wanted to see how much threat this build could generate while maintaining the survivability of a normal Frost build. Arguably, the 2/2 Epidemic is probably the weakest part of the spec since we are spamming IT and Frost performs very well without Blood plague. This build should also have excellent RP generation because of all the ITs while having the 2/2 in Chill of the Grave talent.
Unfortunately, I actually can't try this spec myself for a couple of weeks. I realize that I might be making a fool of myself here or overlooking something entirely, so please chime in with any comments.
Thanks in advance
(Edit: It's a 2-hander build - to make it a DW I'd move points from Icy Talons and IIT to Black Ice, NoCS and ToT -
