OK, I conceive of the unusual case where you might actually want to buy a 3 star player ... but i can't imagine any time when you'd go more than 2-3 tokens for them.
So why do I keep running into these idiots 2 levels above me who want to get into bidding wars over a player who would only be 3 stars to them? Once or twice, sure, but 2 out of every 3 times I hit the market???
Sheer stupidity beyond comprehension? Or Nordeus bots?
This is a case where the conspiracy theory is far more rational than the alternative.
