I'm a little confused about how the combination of Step up, Following Step and step up and strike work together. If a PC has all 3 feats and he is fighting a villain who wishes to use the withdraw action to retreat from combat at moving at double his normal movement rate does the PC with the get to make an attack against the villain if the PC is not adjacent to the villain after he makes his move. In other words the villain will be 60 feet away after his turn is over and the PC can only move 10 feet according to the feat. In simpler terms does a PC with those feats get to attack a Villain using the withdraw action moving at a faster rate that round. If the PC does get to attack how would haste and similar effects work with that.
