I *think* what it is with the tokens is you start getting one per level once you've maxed out the tree. Which by the time you're trying to grind all the prestige upgrades is not really fast enough (but way better than it used to be at 1 every 10 or every 5 it seemed like). Maybe one way to make the upgrades that help you make more money matter late game is to let you cash in $ for tokens at some high exchange rate?
