this is what i do for opener
rake, shred, to 5 combo, tiger fury, rip, shred spam
if u alrdy have rip up on the target and its good duration, use tf with fb
if not, use tf with rip
also, when i pop cooldowns on a healer, i dont usually chain rake stun, i only use rake stun as a filler to interupt when they are hard casting and interupt is on cd
