It's kind of pointless having Light house and the other one being a 5v5 map when i play with 6 players, 2 more guys will not effect these maps at all, especially since Skyline and City hall are similar sizes and hold more players.

^^Please fix this in the patch Cry-Tek, 2 of your maps are going to waste.

All maps are 6v6, what do you mean exactly?

Then why doesn't the map ever come up when I play ranked matches?

Randomness? I've played 6v6 matches on Lighthouse before. Though, that map doesn't get picked nearly as much as others in my experience.
