How are WARs doing 1k+ DPS?

[Tyrial]

blow all your offensive cd's and str pot in your 3 fell cleave window, and alternate between storms eye combo and butchers block combo. Im i190 (all slaying accs and bonus 35pts in str) and do around 1050-1100 sustained. Use your berserk carefully, dont waste it on 2 fell cleaves if you can get a 3 fell cleave window shortly. If I had a healer dispelling my pacification every time the dps would be even higher.

I'm able to sustain this MTing Faust in A1S without doing any triple fell cleave nonsense. Don't see the point in dumping all my CDs just to squeeze in another hit when you can still maintain the same DPS without it.
