Easy - Medium - Hard option in dungeons
Easy and Hard is enough.
If they made the easy indeed easy. When I read “story mode” and “first dungeon in the game”, I expect something else than what I got when I entered AC SM at lvl37. They can make lvl-80 ExplorationMode dungeons as hard as they want. I’ll prepare and learn and spend time and beat them some day. But when I am leveling my character, I don’t expect AC difficulty at “easy mode”.
