You only picked a few there ans Walsall was over 30 years ago so is not a new stadium. Burton was built when they were non league so not comparble. Rotherham etc is more the level of Vale. However you are missing the bigger picture it is more than juat ques. It has so much more to do with the standarda of facilities on offer and also tgw cost of redeveloping VP could be a major issue. If you read further back you will see this.
