I kinda like it, but what is the point of using it if you can't use it well?
Lolwut?
Well, I might not be an energy weapons guy, but sometimes I like to use a Gatling Laser to blast my enemies. I think that this system like that encourages roleplay, so while you can use some other weapons you might as well just stick with what you are good at. If you want to try something else, just do it, but you aren't going to swing it as good as what you are skilled at.
In that way, you can create multiple builds and characters, each one good with a certain type of weapon.
