Agree wholly mate
Personally, i think this is a strategy by the club and eventually the capacity will be 55k after the fan consultation, it will also take it above Mordor, which will sate a lot of our fans.
For me its not about filling or not filling, no doubt we could fill 60k in certain matches, the derby, cup quarterfinals etc, European games etc. But there are particular games we are no way filling a 60k stadium for the likes of home games against Watford, Bournemouth, Huddersfield, Palace, Brighton, Cardiff, Fulham, Wolves, Southampton etc in my opinion, it will be a push to fill 52k, to be honest for those games. When you look at it logically its actually a bit foolish to build anything beyond 50-55k.
You have to physically think of a stadium of 52k size, i dont know if people have been to St James Park or the Eithed but they are the closest, they are fine and huge modern grounds that would suit us down to the ground and we can be proud of the ground if they are similar, i actually think The Eithed and Sames James Park are more atmospheric and electric then say 60k stadiums like the Emirates or The Olympic Stadium. Not to mention our ground is going to be an iconic site. It really could be an absolute Gem.
I am big into the GAA in Ireland and i go to Croke Park regularly, Dublin the biggest team (population 1.3mill) in Gaa play their home games in Croke Park and its an 80k stadium. In early games in the championship or league over here, you are lucky to get 20-30k and the place resembles a morgue. Its fine come a semi final and final, but for the majority of the games there, the stadium is to big for the event and really affects the atmosphere and experience.
