I wanted to post this thread for 2 reasons, to give new players an idea on the rotation and to see if anyone had suggestions to help improve my rotation.
I have ranked in ToT on Tortos, Council, Horridon, and Jin'rokh so i guess that im doing something right
If hero is pop'ed at the start i will exhaust my runes and pop runic empowerment for some extra burst
Army ~6ish seconds to pull
Pre-pot, icebound, Ghoul, Outbreak, and Death and decay (cause I can do it from ranged and it starts unholy rune regen)
Then I go into my rotation, howling blast when frost runes are available and frost strike when KM proc's or when over 76 runic. I rotate DnD, Obliterate and plague strike (when blood plague drops) into my rotation when i have 1 recharging unholy rune and one full unholy rune (this is key and i will tell you why). I also use Soul Reaper on cool down when the boss is under 35%(I dont have the 4 set yet). I try and use Horn of Winter, Pillar of frost and ghoul on cool-down so that they match up and give my ghoul a damage increase(around 70k damage). Situationally I use AMS for free runic power gains, Dark Simulacrum to spell steal ability's (only on Protectors of the endless right now), and Glyph of Dark Succor for free damage/runic if i kill and add.
I'm running Plague Leech and Blood Tap dps talents
For these 2 talents I make sure that I only refresh Frost and Death runes. Refreshing Unholy runes would be a dps loss and force the use of Obliterate, DnD, or plague strike. To make this happen I only use Oblit, DnD and PS when i have more than 1 Unholy rune and the 2nd unholy rune is almost finish recharging. the frost runes are used to howling blast more often.
Plague Leech needs to be used with ~1-2 seconds left on Dots
an Blood tap is just to fill global's in the rotation
As far as addons to keep track I use:
Tell me when: for ghoul/pillar of Frost/Horn of winter/Runic empowerment to show when they come off cool down
Weak Auras: to track runic power and Rune regeneration
For good Runic Power and rune regeneration Weak Auras go to orranthrall.wordpress.com/2012/10/20/dk-weak-auras/ its just a world press that someone was nice enough to put up. The trackers are easy to use and very easy to modify.
