The way this game has gone (and even before, last year, 2015, which is was among the reasons why I quit), considering the way some fixtures are set up (3 matches a day, with at least 2 close to each other), all those excessive injuries, and now the excessive, draining trainings that must be done, this game has become more of source of annoyance. I faced difficulties maintaining my team in good condition this season despite having bought tokens.
And yes, the recovery (+6% every 3 hrs) is not sufficient at all. Many other users are not facing this problem because it seems that they earn a lot of green packs a day (some as high as 50-100 green packs a day), while users like me can't earn even one green pack or token. So, I have to buy tokens and turn them to packs. But, there is a limit to everything. I think that what has happened to me lately is above the limit. I had a lot of injuries from matches in this season despite having maintained the players in good condition (dark green) most of the time, and many of those injuries were lengthy ones (6-12 days). At the start, I healed the injuries, but then I could no longer heal them because of a lack of red packs and tokens. I already bought enough tokens and cannot buy more as the credit card account is exhausted (no more money available) for now.
What is occurring is surely a business ploy by the company.
I already though of quitting this game again after what has happened lately, especially because of those excessive injuries and suspected fixed matches or predetermined outcomes.
