Recently started playing again, have a few questions

[Dogbert]

I completely forgot wizard and witch doctor offhands and two handers.

Oculus/Chantodo/Triumvirate/Tal rasha beat any rare source.
Thing of the deep/Uhkapian beat any rare mojo.
Skorn beats any rare two hander.

It's sad that it's basically impossible to find a rare source worth something. It has to compete with all four of the above mentioned sources. :(

I pick up all rares, gems & tomes.... An inventory full of rares is about 50k, 3 or so of those per run adds up nicely.
Id,ing them takes time but stops me going crosseyed too.

If speedily gaining Exp or something is the goal, it's best to skip rares. The level 63 in a few slots are still worth it, but ultimately you're faster if just focusing on Legendary / Set.
