Most of the times when it is a prerequisite, the build is usually quite mobile. Even when they are not, the benefit tends to be superior to regular dodge at most times. I mean most races have 30ft Movement speed, and getting +10 speed is quite easy from itemas/class features/spells, or even from Charging for any melee character. You wont be moving every round of course, but even in cases where you are activating it every other round, it is still effectively providing an equal bonus against one opponent. Against multiple opponents however, you will be taking far less hits across the board.
If not as a prerequisite though, no point in taking this feat, or its 3 other variants. There are much better options available.
