The community can't be changed so any system that could motivate players to improve or match players of similar attitude together would be worth the risk.

I am totally behind the game calculating in-game score. It would be tricky to get it right with all the item levels and mechanics that should contribute to the score, but it would be at least a step forward.

Right now there is almost none accountability for being lazy and exploiting the rest of the group. This should be changed.

Totally okay with players who semi-afk in dungeons and watch Netflix, each player pays their sub after all, as long as the contribution of said player is highlighted for everyone to see. All the party members deserve to know who is making their lives harder/easier.

And I get it that this would lead to some elitist players stroking their e-peen - but these players can be effectively reported. People who silently seek carry can't be banned for wanting to be carried.
