Thanks everyone for your input.  I ended up creating a Grav/Energy, because I wanted to throw forklifts at people, amongst other things.  At 20th so far, she plays indeed a lot like a blaster (based on what powers I've chosen so far), which is easy peasy-playing (so much so, I haven't leveled a blaster past 20, too dull overall).  Now that I'm starting to get near the exciting Grav powers, this "feel" should change.
 
	 
 
	Dark was a very close second, so maybe I'll go for that one one next.  Or Plant; never played a Plant.
