When i fury with my mara I found this rotation to be the most optimal to get the best out of cascading power windows.
Rage up.
Opener:
Berzerk, charge, burst, force crush, ravage (clip it at 0,3s with), fury strike
1st cycle: Battering assault, obliterate, burst, scream, slash, fury strike, slash (one of those is Vicious throw below 30%)
2nd cycle: Berzerk, olbiterate, burst, force crush, ravage (clip it at 0,3s with), fury strike
Just repeat those 2 cycles rage is in abundance, the most i hit with it was 4,6k with really lucky crits, otherwise it's consistent around 4,2k 4,3k in a mix of 186/192 gear.
Really easy rotation out of the 3.
