I'm currently upgrading my gear to kill Belial and progress further, but armor and resistance is confusing me. I'm firstly going for 100+ vit and int on gear and then I'm stuck at choosing whether to choose high armor or high all res.
If you have the same damage reduction from armor and resistance, then one resist all is worth 10 armor. If your damage reduction from resist is are lower then your dmg reduction from armor then it's worth even more, and vice versa. Armor is rarely better.
