So… I don’t know if it’s a real bug or if it is intended so, but i just got matched in my daily mission dungeon with someone 15 lvls over me. Not only did I gain less than 20% exp the whole dungeon but since I’m not a token user i kinda “lost” 1 out of 2 runs.
Even if matchmaking is intended to be so, I think I’d rather wait longer for someone around my lvl to queue up than to go in with bosses +10lvls over me (who actually did one-shot me twice) and finish with only 20% more exp.
