Hello!
From what I heard Grim Dawn lacks a bit in end game content after the campaign. It mostly comes down to farming caves and the same thing over and over again. That is ofcoure something I could live with, BUT somthing like the D3 rifts should be something real nice. Big ass dungeony like things where you go in with your buddies or alone and just kill a ton of monsters and get loot.
Probably this is something someone had said before me but just wanted it to be said. Love this game and would love as much end game content as possibly to keep playing for ages!
