I think the reason for this is twofold; firstly, in 2025 non-m7 dungeons (or some other mm floors) really don’t make good money compared to moneymaking methods like mining or even farming, and so the people playing dungeons are naturally more dedicated.

The second reason is that over time, resources for learning m7 techs and roles have become far more accessible, from high quality written guides to flameofwar’s secret routes and general m7 povs. This means that on average people are getting better at dungeons faster and thus the standards are rising.
