Instead of forcing players to play a certain amount everyday go to a monthly cycle for the recurring daily events. (This would not effect the adventure board, the dungeon or the weekly guild events.) Every month every player would have a certain number of daily faction events and daily class trials. You can have more than 1 going at time, but once you start one you have 24 hours. Faction events or class trials for new classes or factions would not be impacted by this since they come when they’re ready. I’m only referring to the recurring ones for existing classes and factions.
That respects the fact a player just may not have time today, but may have time tomorrow.
