How can you kick your community's nuts so hard?
It is absolutely unnecessary to wipe progress if there are still people who can play and enjoy this game afterall.
One cannot simply say" 'Cause we want fairness to new players". These players will uninstall anyways if they dont like the game and so will the others when permanently wiping progress such as XP. Also it is a simple and proper way for new players to get carried by more experienced ones.
As usually well done Russian/Ukrainian developers.
Cheers.
