It is my mind that, "I will stop after 15+ tokens", but since I haven't spent on it yet, I keep going. It's the moment when that value sinks in.
Sure you can buy cheaper players, but for a casual player like me and many others,
I don't like spending time, rest packs, and effort on one player that will only probably play 2-3 seasons, unless I keep training that player every single season.
Tanking is also a choice, but it is also time consuming.
Hope you understand my point of view here.
