Trust me, when you get to higher levels you'll find a lot of people who buy tokens and they will go to great lengths to buy that player because they have a lot of tokens. It is not uncommon to see people bidding over 20 tokens but this is a waste and Nordeus loves these kinds of players. If the player is really worth it.. Close to 6*, special ability, 18 y/o with fast training speed.. Then yes it is worth it. But if it's a 25 y/o 5*, I'd probably stop at 10 max...
