As an experiment/test, i wanted to find out how much upgrading/badge generating 100,000 stamina could do under normal circumstances.
The tragic answer is, not very much!
It wasn’t even enough to get me a third Red.
Now I am signifigantly concerned that Stamina is imposing an serious impediment to character upgrading, if this rather simple upgrade consumed almost all I had.
The only way I’ve been able to upgrade characters is to use purchased stamina consumables and when I realized I was spending in excess of $30 a month on those items and using every single one, I had to give it up because of the cumulative cost being too expensive.
Honestly, based on the results of this expermental test, the only conclusion I can reach is the game is unplayable because characters are too expensive in terms of stamina to upgrade, so they can’t be upgraded to match the enemy team difficulty.
