The old rotation won't really be complete without Chaos Thrust @ lvl 50

So, up to 49 just follow these rules
1) Keep Heavy Thrust up and don't clip early
2) Keep Disembowel up on the target unless it will die in a couple GCDs (i.e. Very weak trash)
3) Keep Phlebotomize up on the target (Unless, again, it's about to die) and don't clip early
4) Use your buffs (Internal Release, Blood for Blood) and Life Surge only on Full Thrust
4) Use your Jumps and Leg Sweep

...Or just FATE grind in CCH and then Northern Than and do whatever the heck you want lol
