Level 50 Rotation

Heavy Thrust > B4B > Impulse Drive > IR > Disembowel > Power Surge > Chaos Thrust > Jump > Phlebotomize > Leg Sweep > True Thrust > Dragonfire Dive > Vorpal Thrust > Life Surge > Full Thrust > Spineshatter Dive

Level 60 Rotation

Heavy Thrust > Battle Lit + B4B > Impulse Drive > Strengh Pot > Disembowel > Internal Release + BotD > Chaos Thrust > Power surge + Leg Sweep > 4th > Gierskogul > Phlebotomize > Jump > True Thrust > Dragonfire Dive > Vorpal Thrust > Life Surge > Full Thrust > Spineshatter Dive > Repeat

*4th = fang and claw/Enhanced Wheeling Thrust
*B4B = Blood for Blood
*BotD = Blood of the Dragon

I would add this:
while your Blood of the Dragon is on CD, which is about 1 minute, you want to use Gierskogul 3 times before using BoTD again. I think the key number as to when you should use Giersokogul during your rotation is when BoTD is at ~21 seconds, depending on latency and/or skill speed.

Sometimes I even use Battle Litany before HT just because I can't double oGCD and Elusive Jump towards the boss at start of a pull, for the shits and giggles and getting into the rotation faster.

Otherwise, that's spot on.

Thank you Drako for your wall of txt ;P
