I do not know if they will but Nordeus' guess is definitely this one. As we do not need blues or reds anymore, the only way for them to get tokens paid is to force players to buy greens. You just have no choice if you play 2 games per day and want 10% bonus. My green tank went down from 1900 to 1500 in just 2 weeks as I only get 2-3 packs a day when it used to be 40 or even 100.
