East Stand Upper, Wings?

After reading the price rises of Season Tickets, why isn't there an ESU wings price? I'm out in A block ESU and pay the same as someone with dead central seats. Also directly opposite me is one of the West Upper Wings. If you have a wings section on the West upper, why not the East upper? I don't think I should pay as much as some of the central blocks of the East Upper. Will the club review this pricing imbalance?

I will pass on your comments, but I would point out that part of the wing areas in the East Upper, are taken up by the disabled areas at either end.
