It should resist fighting though.
Anyway say we get an awesome light typing and some great new mons with it. What's gonna happen? Everyone will use them and people will complain about how old Pokemon aren't usable and people are only using the newest gen. Which is EXACTLY what happened in 5th gen so I know it would happen again.
Thats why old pokemon would retroactively become light type, such as ampharos and lanturn...
and Light type wouldn't touch dragon types, It would be resistant to more prominent types and be weak to less fortunate types such as poison, grass...
it would balance out alot of types
