Close Blasts and Forced Movement
Here's a scenario:
A character uses a Close Blast 5 power with Effect: move targets 3 squares away from caster. The only targets within the Blast effect are 5 squares away from the caster.
Does the power really move them a further 3 squares away?
I can see no rule that would suggest otherwise, so I would have to assume that is the case, but it seems mildly against the intent of the Close Blast.
(Then again, the push probably shouldn't stop at the edge of the Blast for targets that are 3 or 4 squares distant; it's just odd imagining that a target at the extreme edge of the Blast would be pushed well beyond that edge.)
