personally
i think around 700 is an ideal amount for warrior if you're talking about skill speed
because when i reach that amount i was able to add 1 more fracture attack at the end of my burst rotation after i'm done doing fell cleave
and when i'm doing the triple fell cleave burst rotation i am now fast enough to add one more butcher block attack at the end of the rotation(when i'm at 600 it ends with me not being able to do another butcher block attack)
