Those really high res is mostly barb/monk.
Range classes I think about 300-500 is considered alright already.

Im working toward 500 all res myself, now about 230.Ppl said glass cannon built...blabla.But glass cannon is just not my style.
Also worth noting socketed helm could boost your life with up to 18% providing that you put in a maxed amethyst, freeing up some need for vit.


Different ppl different methods.Myself, I mitigate dmg with high crit chance and high crit dmg.So, weapon with slot is the best with potential to have +100% crit dmg.

My ideal dh goal is 2k main attribute, 40k hp, 500 all res with high attack speed crit chance and crit dmg.
