Smaller clubs deserve success too and it's a great story... people were also complaining when Sassuolo got promoted and they stayed up and are holding their own. I agree about wanting to see Pro Vercelli back in Serie A though, as it's been decades, hard to imagine they were once such a successful club.
Of course if you get promoted fair and square then there is not much to discuss. Personally though then I believe that clubs like Carpi, Frosinone (they look likely to be promoted as well), Sassuolo, Cesena, Empoli etc. don't belong in Serie A. I would much rather see clubs like Bologna, Pro Vercelli, Parma (now that they are relegated), Bari, Brescia and Cagliari (they are too likely to be relegated) in Serie A than those aforementioned clubs.
I personally like to see traditional clubs with large fan-bases instead of tiny clubs like Carpi, Frosinone etc. on the long run.
Just like I prefer to see clubs such as Real Zaragoza and Real Betis for instance rather than Eibar and Granada.
I guess that I value tradition more than the average football fan.
