1. You apparently can't read potion descriptions[+20%, max 84], the max Str we can get right now without Gordian slaying is around 880-900, so +20% isn't too inaccurate. Opening rotations are tooled to interact with as many potency buffs as possible, forgetting something as powerful a potion can seriously skew numbers. Example, I get 2x Fell Cleave and Fracture in my XPot cycle, you do not get the Fracture. This discrepancy will increase the more common Draconian potions become.

2. Your "other" rotation has Eye falling off after the third Fell Cleave, losing about 62 potency more, unknown amounts to the autoattack during as well.

3. You extended your rotation 1 GCD past mine, in order to fit your 4th Fell Cleave in(which you are several GCDs behind on, I wonder why) in order to pad your potency. Yet, despite all the errors, behind mine.
