I don't think i ever noticed that, I just traded out Quick step at 7th level for it because I felt like it would be more useful, i misread it as a minor action and not a move action.Wow, looking at your power selection I just realized something. Repositioning Maneuver is actually worse than Careful Positioning. It shifts 1 square less and is a daily power. I'll need to figure out something for that.
Lightning Assault is a max of 4[W] damage, with the stat mod twice, against multiple targets. Considerably stronger than a wizards 3d6 fireball, despite the lack of range and only close burst. Also compare to the ranger's two wolf pounce, that gives 2[W] and 1[W], with a secondary 2[W], but all against single targets.Very good reason, but it make's me wonder if the power is a little to strong then.
