Yeah, with the new associations rewards system it is a bit harder to earn token, generally speaking.

To earn the 100 token you got before quite easily from staying in platinum, you must now play in diamond division and (on average) finish 2x 2nd and 2x 3rd there, which probably doesn't even mean you are going to stay there and could go down to platinum...
Also it is quite hard to find a diamond or ultimate division if you don't have the x3 association bonus, for which you must have finished at least 3rd in the league the season before.

For me personally, the new association system isn't really bad, but there is no doubt you now get fewer ressources/tokens than before and you have to work a lot for getting them.
