Well I didn't think I would ever find myself so firmly on the opposite side of "The Bringer of Headaches", but I am

A 45% speed buff that's up over half the time doing my regular rotation is very strong in my experience. Yes, its not always up at precisely the time I would like it to be, but it usually is. Even when it isn't, it is (at most) about 2 seconds away from being back. As my gear increases, so too will its utility. I am not suggesting that one should ever hold back in their normal rotation for a speed buff. All I am pointing out is that with a large amount of haste its never too far off.
As my haste increases more it comes back all the faster. I find myself zipping around more effectively than with any other of those movement based talents. Its also nice to not care one whit about how much HoPo I am carrying and just slam as many ShoRs as I can into the boss.
I honestly think that over time (specifically with a haste build) there is no other movement talent that one should even consider in that tier. Except on a fight where you want to move really fast every 45 seconds.
Lets chalk this one up to "check back later"

I do think it is fair to point out that Haste does make it a better choice, even if you want to argue that its not the best choice.
