Personally I like the infuriate to be the 2nd fell cleave, so popping it early allows for a bb>SE unchained>berserk+IR>deliverance>str pot>fell cleave>infuriate>fell cleave>SE>veng+RI>HS>Maim>fell cleave>Sp. Granted, I sit at 620 skill speed and if I do it without clipping, I get that sp in before pacification(not necessary though with my FC static; healer knows to esuna). Then I drop fracture>SE>SP>SE>fracture>SE>SE>SP>fracture so forth till the CDs are ready for the fell cleave combos again. Granted this is me personally, and other warriors with diff stay builds will do it other ways
