I'm beginning to like this idea.

Lightinfantry with a speed boost would rock.
And instead of the beam, possibly lightning shoots out to the nearest enemy near you, doing a nevermiss hit for say, 10 or 5 damage?
And if you swipe an enemy at 80+ energy, you'll do 5 extra damage which jumps for up to 2 enemies within 10 tiles of that?

Make this dual wieldable. D could be a block, which consumes 1 energy a second, and every bullet you block takes away dmg/1.5 energy. Then this'd be a damn good weapon.
