If the only change they made was make IR lower de cost of Upheaval and Onslaught, but have Fell Cleave cost 50 points with doubled potency:

HS (Infuriate) -> Maim -> Eye
HS -> Maim (IR+Zerk) -> Fell Cleave (Onslaught) -> Path (Upheaval)
HS -> Maim -> Path -> Fell Cleave

We're then left with a few seconds on the clock for Inner Release after which we Onslaught before it wears off, but we'll start building points back sooner and Storm's Eye won't have a chance to wear off. Another advantage is that there's no way to fuck up and miss a last FC and end up with unusable points.

We'll get to start building up points 2 GCDs earlier.
