I don’t think so. You do remember that this game is a mobile game? It is simply a thing of how big it will be on your mobile.
And tbh I never had an RPG where you can replay quests when they were not daily quests or anything that can be repeated because of their ingrained nature.
So: I think we will never replay quests. Make a new account or follow e.g. Abraxos, SarahKey or other content creators on Youtube who post their story quests as videos. 🙂
