If I may make a suggestion…
Some of us players who joined after the game was started missed out on a lot of previous dragons and evolution stones etc etc etc
I would like to put it out there that maybe in the future you could offer green gold and maybe even platinum evolution stones as prizes during the events that are universal and can be used on a dragon of the users choice, that way if a person has a dragon that they really like flying but won’t be useful as the player levels up and progresses this will give them the opportunity to continue to fly said dragon in future endeavors. I personally have a couple myself that have become null and void as they are no longer effective.
I’m not suggesting a stone for every event every week but perhaps one stone a month maybe? And also not making it so impossible to achieve so that lower level players such as myself can still acquire a stone without braking the bank doing so
