Blood Presence 2H - 16/0/55
This build has kept me in the top 3 on many 10 & 25 man (pugs); the rotation provided workers like a charm and is easily macro'd for optimum movement and positioning.

Imp Unholy Presence 2H - 14/0/57
This build allows me to surpass the damage of 16/0/55, by a large margin; based on my current gear and lack of haste; as described in the OP.
Question: The 14/0/57 build does not allow for the proper use of HoW in the posted 2h-rotation; I'm left using other means to generate RP (Blood Tap or Empower Rune Weapon) so as not to have the HoW timer limit my rotation; is there a rotation which would allow the use of HoW without running into it's timer (many times there is a 3 to 5 sec wait for the HoW timer) ?
