One square can make all the difference in the world. Pull someone into position for flanking. Pull them AWAY from flanking so the enemy can no longer sneak-attack one of your buddies. Pull them away from a friendly artillery so it can shoot them. Pull them next to a bunch of your friends so they can easily unload on someone because now more squares around them are empty. Wreck your foes' clever defensive positioning.He has an encounter power that blasts an enemy with radiance, then marks them; and a minor action (at-will, 1/round) that pulls the marked enemy a single square closer, though I shouldn't think that one would ever be particularly handy. I mean, you already marked them, so what's one square really worth? His last encounter
The possibilities are vast.
