Actually they've been allocating the same for the last three years since the new Wembley opened.
In Cardiff the teams still got around 25,000 tickets each but the stadium has a 15,000 smaller capacity so proportionately there were far more "real" fans there....66% against 55% at Wembley.
Don't know what the proportion was at the old stadium but it was certainly better than it is now, because there weren't 17,000 "Club Rich Bastard" seats...and the capacity was bigger again (not towards the end). I'm proud to have been part of an old fashioned 100,000 crowd there .
