Thanks, please let us know what that discussion on our feedback concludes.
Especially concerning:
. The rank names: current system is not coherent, in the real world the words “Guru”, “Master”, “Mentor” and so on refer to the experience of a person, not on its ranking among its peers. So, to be really meaningful, in CG rank names should be attributed according to the XP of the player, not according to its ranking. Another option is to rename them, or to remove this concept.
. The possibility to have a leaderboard for people interested in solo puzzles only. This activity is key to lot of people here and to most newcomers. It deserves its own leaderboard and this is quite simple to implement.
