Im sorry, but i dont know what you people were expecting.
You want to have the biggest, most popular league in the country that everyone wants to see?
Well, this is what happens. Demand for tickets is high, so the price goes up and people will still buy them.
I know people like to paint themselves as the victim, "20 years ago, when no one cared about the game, i could get in to games cheap. Therefore, i should still get cheap tickets now. Because logic!!!!!"
The game doesnt owe you anything, because of your loyalty. You were around before they were popular so you took advantage of cheap prices. Now the quality of the game is through the roof, you either pay the current price or just dont go.
