It would be great if they put some side quest for classes like cleric, paladin or warlock. For example: If I create cleric. Maybe some times after long rest (from time to time. It will be silly to be every night) my deity (or maybe His messenger like angle or something) comes through some vision in my dreams and gives me some side quest to do for him. It feels like those spells that we can cast that deity give us are without cost. We should do something in return. Same goes for warlock and his patron. Also maybe I am asking too much but what if we don’t do does side quests and ignore them. Maybe then we can’t cast spells anymore. Of course not of the rest of the game but maybe until we complete some like redemption side quest.
