Not necessarily. Everyone is like "OMG LIGHT TYPZ!"
But realistically it could work. The only type that doesn't have a "supereffective" going for it is the normal type. Now the point of that is, that while taking X2 damage to fighting, it takes nuetral to everything else. Normal type has immunity to ghost though. You could easily put light type in there to where Normal is supereffective against light. And Light is nuetral to everything else. Or does supereffective to Dark, ect.
It COULD be implemented. But it WON'T be.
See? Right there is why it wouldn't work. It would realistically be only effective against Dark types. It would be neutral to everything else. That is a waste of a type right there. You would have to restructure the entire type chart to even remotely have a chance of it having a slight possibility of maybe working.
But I agree, it WON'T EVER HAPPEN.
