It's probably a stupid question but I just need to know.. I have a 5* player and after 2 more skill points he'll become 6*... Can I still use him normally?? I don't have to pay tokens for him like he's a scout right??
No, you will not pay xtra T for him. But his value/wage and sign-bonus will increase with some percentage (%).
And you will be able to use/play him as before (but he will a slightly better)
