Making a token system simmilar to brawl stars is something that could be cool. If you dont know what it is. Instead of tokkens being given to a random character it instead goes into a big pot of tokens. This wil let you choose who to uppgrade as long as you have coins.
Also to even things out you could add a token limmit so if you reach like 50-75k tokens the tokkens you get will be converted into coins.
Then we should also change the conversion scinse 1 tokken - 600 coins
Instead 1 tokken - 100-200 coins
Second idea
You could also make a seccond currency that gives you something called super tokkens witch you can keep stored and use on any character in the game.
Super tokken chanse could be like
Gold crate
10% - 10 tokkens
5% - 15 tokkens
1% - 30 tokkens
Emerald crate
25% - 10 tokkens
10% - 20 tokkens
5% - 35 tokkens
1% - 50 tokkens
Legendary crate
100% - 50 tokkens
50% - 100 tokkens
25% - 125 tokkens
10% - 400 tokkens
1% - 1000 tokkens
Black create
100% - 250 tokkens
50% - 400 tokkens
25% - 850 tokkens
10% - 1000 tokkens
1% 2500 tokkens
Legendary black crate
100% - 750 tokkens
50% - 1500 tokkens
25% - 2000 tokkens
10% 2500 tokkens
1% 10 000 tokkens
Theese numbers could be discussed 🙂
