Both should go together really. If the league was expanded to 16, it should happen with a big promotion drive for the league. You have a good point regards Rovers/Boh's getting bigger crowds for those games than Bray/UCD. If Rover's/Boh's weren't playing so often in a year though, the one-off trips each season to their respective grounds could attract more support. An expanded Premier covers more regions of the country and raises the profile of the league nationally. Expanding the league isn't enough though. It'd have to come with a big promotion drive for the league. The proposed expansion to 12 isn't much of a revamp.
