Archer. Their arrows can be anywhere.
Grappler. With enough movement-based powers, they can fling enemies all over.
Spear-user (pikeman?). Reach + movement-based powers = nothing can escape the reach!
Alchemist. Your grenadier, chucking acids and alchemist's fire and releasing clouds of ick.
Swashbuckler. Dropping chandeliers, tying people up in tapestries, moving around pieces of terrain.
Taunter/Manipulator. Enemies move based on the things you say and the authority of your voice.
Wuxia Martial Artist. Punch the ground here, earth erupts in a shockwave over there. Fly through the air to reach your target. Use exotic weapons that trip, disarm, rush, etc.
Combat trixster. "I'm over here! No, I'm over here!" Throw your voice, juggle your weapons (thrown daggers, or other implements that cause trouble or pain), use caltrops and booby traps.
EDIT: One more: The Yo-Yo Master. Basically a user of whip-like rope or chain weapons. You throw the blade, you reel it back in, you tie people up, you swing across chasms. Works with a whip, and with some of the more asian-flavored chain weapons.
That's more than enough to fill a couple o' PHB's, and it's not even very exhaustive. Basically, use any ranged attack, or give them powerful movement abilities (or the ability to move enemies), and you have the ability to take the battle to the enemy wherever the enemy may be.
