The only thing I really want implemented in Grim Dawn is an official mode with reduced exp gain and less shrines, like the mod I made for 1.1.9.7. It could be a toggle for all difficulties, similar to Veteran. The idea is to revive the spirit of the good old days, when you had to properly play through all three difficulties to max out your build. I slapped it together in a day or so and it actually works just like I wanted it to.
I haven’t yet updated it for 1.1.9.8, but I plan to keep it updated.
