just a thought, and I maybe wrong, that fairy tale advents were bought into the game for those sitting around on level +50. so that they had new advents and rewards to strive towards.
maybe the fairy tale advents should have been set for players level 50+ only. some lower level advents also have a minimum level requirement to play certain advents. so this could be done.
Otherwise the fairy tale advents were just introduced into the general game, for any and all. effectively defeating the purpose of rewarding the highest level players.
