I'm probably one of the lighter-hearted bearers of ill will, so I'll be the first to say that a lot of JJ2 gameplay comes from choosing and aiming various different weapons. Blaster, from what I can tell, isn't used all that much except in cases of extreme fastfire and (preferably) a powerup, or when I'm facing a total newbie whom I can beat by using blaster against all the weapons in the level. You had better have some interesting ideas in mind to take the place of all the weapons.
