Not going to happen. Customers who are bad and don't want to get better will stop being customers. That seems to be SE's stance. When you have dungeon bosses where a single player can solo them because the outgoing damage is that low or bosses where when the tank and healer die, a DPS or two can finish the last 20% of the boss off... Well, the difficulty is low enough that you can carry someone not even playing through the content, let alone one who is poorly geared and playing poorly.

Getting paired with a DPS who doesn't know what AoE is when facing 10+ mobs is just something I expect these days.
