Mouseferatu said:Yes he did. While both take your move action, a "shift" and a normal "move" aren't the same thing. The player should be telling the DM which he's doing under any circumstances.
Yeah, you can't actually do this. It's not like attacks in 3E, where you could make your first attack and then decide whether you wanted to finish out a full attack action or use a move action, it's like the difference between declaring a 5-foot step and a move in 3E. You can't start one action, then retroactively change to another.
Also, if it was a normal move, the player is even worse off because he provoked an OA, and the fighter's attack stops him before he moves away, leaving him adjacent to the fighter. If we assume the character in question already used his standard action, "switching" to a move would leave him with no way to escape, whereas the shifter has at least escaped melee range with the fighter.
