1. You are already rewarded with a win, I think that is enough.
2. I don't think all items should be bought with cash, maybe there would be some different items that you can buy with cash but not current ones like shirts and premium logos, that would be too easy to get hold of
3. Again, cash is too easy to get hold of these days. From the Cup alone, I got about 11M this season and i'm in level 3, how many tokens would I get with that? Far too many, Nordeus would lose money that way
