Good luck, if you are looking for early endgame setup, then check my Warden, [1.2] Beginner’s Retaliation Warden - Grim Dawn / Classes, Skills and Builds - Crate Entertainment Forum.
This version for Commando (prioritize resistances on green gear) Commando, Level 100 (GD 1.2.1.0) - Grim Dawn Build Calculator. Sadly, it’s just weaker version of Shaman, still should be tanky enough for hardcore to farm all endgame gear. I don’t have pre Champion of the light guide, because there no point to play retal until it.
