If you charge $200 for something, only one person will but it. If you charge $2 for same thing, 1000 people would buy it. Which one makes more money and has more happy people. Just saying.
All wait times for each level should be the same. Level 2 = 2 hours, level 3 = 3 hours and so on.
Level the playing field and everyone will be equal at some point or another.
Most of us don’t have hundreds of dollars to invest in a game.
