I understand security concerns but given the crowds and WPS saying there have been minimal problems, it seems a bit odd to assume a riot or something will break out because some fans cant get into the party.
They could always open it an hour or two earlier and use social media to alert when close to capacity. People wont come down if they know its full. And will instead spread out to local bars etc.
The ticketing system simply doesnt work. People buy maximum in case they find friends that want to go. Its not accessible for all people. And its a lousy PR issue.
Just go back to normal for Game 5. It might be the last one anyway...
