you are too smart to understand that the choice of builidng arenas very big(40k,not 10-15 k as the yours),gave too structural advantages as the system is now.This is becoming the "Right Choice",not one of the choises to develop the game of a single user.
@CrazyEye:The market is global,the discussion of incomes have to consider the differences between the various countries
The other way , you want to punish people who planned for a long time, when they start to get their advantage?
You don't punish the short time thinkers, who got their succes, and even could build their arenas and you forget also, that building arena could help you catch up to etablish teams, i just say flying munchkins. With a big arena is it much easier to get the necessary money you need for a top S5. So make your choiches, but you could compete even with a long term plan.
