There needs to be an avenue for Georgia and Romania to get into the 6 Nations. Should be a relegation/promotion playoff between the bottom placed 6N side and the top placed 6NB side each year.
Georgia are ahead of Italy on current evidence and lightyears ahead of where the Italians were when we first let them in.
If you do that, you kill the franchise of both countries, the top 14 and the premiership will take all the good players.
