Would you buy max level boost from the store if available? I think actual boost to 50 is a bit silly and the price should be much lower. 1-50 is like blink of the eye. Sure 50-60 is more or less same but still. Ofc this should be available when you have at least one max level toon.
*To be precisley. If boost would be to max with a lower price. Actual boost to 50 is damn overpriced. If max would be i want to see it in lover than actual. Only this way make sense imo.
