Confusion ove Dazzling Acrobatics power.

[Family]

This Rogue power is useful in that you get to shift twice your speed. But when would you be attacked while shifting?

Dazzling Acrobatics UTILITY
Move Action, Personal
Effect: Shift twice your speed (climb at full speed). If an enemy attacks you while you shift, you gain a +4 bonus to AC against that attack.

off the top of my head: readied actions, fighters, and I'm sure some monsters out there have immediate attacks they can make vs. somebody shifting.
