Okay... so lets see...
Barring Thundercloud procs, a standard rotation is most often...
F1x5*1.8, F3x2*1.8, B3*.7, T2, B1, F3*.7 = 2840 using the current potency values.
With the new values we would have... 3140, which amounts to an increase of 10.56%.

Still, really wish they would address the whole movement issue... Hell, just ACKNOWLEDGE it! It feels like we've been saying that the biggest kick in the ass for BLM is the new wave of movement heavy fights which tend to cripple our dps until we KNOW the fight and can do it in our sleep... Nope, no mobility fo joo... But here's 10% more dps as a consolation prize.

IDK... Im slightly disappointed.
Well, maybe they ninja fixed the UI tick issues... IE sync it to the character NOT THE GLOBAL CLOCK... One can hope I suppose.
