The game for f2p is basically unplayable due to the evolutions. Only 2 evos per year is crazy. I would love to have more grindy ways to get all the evos of prior seasons. It should take some work and time to get one evo, but not as much as right now.
Additionally, I would like to have gold chests to take 7 hours to open because right now that 3-hour chests are no more the standard chest, I always end up opening 2 gold chests per day since the third one always finishes 1 hour later than my sleep time. Having 7h chests would allow many f2p players open 3 chests per day, instead of wasting many free hours during night
