Solo vs group play

I like the solo experience and feel like the game is better tuned as a solo.

However, the progression is a lot slower. It is a journey, a fun one, until you can kill elites with the loot you get from shaff.

This is all well and good until groups trivialize the content and are decked out in full blues/purple so PvP is a no go.

Shouldn’t mob densities and stats scale for group play, at the very least?
