im considering starting one with no reruns at all ofc
which chars are the hardest which are the easiest?

This answer might be a little generalized, but melee characters would likely be the hardest and casters would be the easiest.

I'd say easy =
Sorc/Trapsin/Ele Druid

Hard =
Barb/Melee druid/amazon

Most everything else would be in the middle imo.

was thinking the same

i would also add summoner to easy imo
im just not sure which char i wanna play

This

easy mode would be trapper/summoner.

Idk, single pass with a summoner, you're gonna run out of bodies to use for your army. Unless you S&E after each act or whenever ofc.
