I made this topic mainly to gather insight related to what players like most about other specific ARPG’s and how these ideas can be applied to Grim Dawn.
For me, Diablo III caught my attention for quite a while, but the lack of build diversity eventually turned me away. Despite this, I loved the treasure goblin aspect of Diablo III. The mechanic certainly needed some improvement (chasing them around is a huge pain in the butt), but it added a sense of randomness to the game which I found to be extremely rewarding. I always found myself wanting to play more, knowing that a treasure goblin hoard could be right around the corner. I think that Grim Dawn is heading in the right direction by improving the loot of Treasure Troves and making them more random, but I would really enjoy seeing specific hero monsters which have a high chance to drop great loot. This would give the player another reason to comb the world thoroughly rather than doing repetitive boss/nemesis runs.
