The truth, is that, the market should have a system with a limit of rounds... let's say 100, but 100, no more xD
The better use for Tokens in the end is buy greens, 75 greens are aprox 75T that is 1 star so... I don't know the system that should be used, but too passed 50 rounds till the 100 the "looser" should recovery the half. In my opinion, as said, as tokens are a main tool to buy boosters for a real improvement once one have the good players....
And this to do not mention the connection closed in the round 256.... lol
