You mean 'big name clashes'? Then I agree with what you are saying.
My point was more about the Finland-Russia or Ukraine-Macedonia games, too many teams that are just happy to be there. With only 16 countries, over half them would at least feel they have a chance, there would be none of this 'best 3rd' stuff which then makes teams play for top 2 in the group, not just 'beat the other bad team'. It's not about the big names, but about the teams in it to win. Denmark as a prime example, Swiss as well, they are not the big names you mention, but made the tournament better. too many teams=too many games not worth it
