I'm surprised that there aren't more people checking the higher spending boxes (Since I think it's an anonymous poll).
But then I guess once you have an awesome team, you don't really need to spend many more tokens to continue improving it. Rather an initial investment, and then just sorta maintaining and tweaking it.
For myself, I don't want to spend money on this game because I don't want an unfair advantage. Although I've spent a few dollars (Around $15US) over 3 seasons, mostly on logos/jerseys, however will admit that I also had a few tokens left at the end.
I am pretty sure though, that if I get to some of the higher levels, where there are a lot of token buyers + video watchers, that I'll have no hesitation with levelling the playing field. As the amount of money spent is tiny compared to the amount of time/enjoyment which can be had (Although if I have a lot more tokens than other players, then I'll feel like I have an unfair advantage, and my enjoyment will decrease).
