Honestly I agree a lot to this. Some of the mission generating doesn’t make sense, like how Ash Forest is a *5 mission but Ashen Graveyard is *4. Another idea of balancing the rewards that you get from it. Tying to suggestion gave in this post about the mission reward rework, the idea of quest token could be a way to eliminate the wait four hours for a E mission that could potiential give useless items like sticks.
Another thing is that we could maybe do a mission board in each region, and have a different spawn period for them. For example, Exbel can have more common mission spawning time, since most dungeons, apart from HT and AF/AG (maybe SA at the greatest) doesn’t offer as much points as for example, archford where the board can give higher rank missions but a much slower mission spawnrate.
