[2.6] Oro's Molten/Flicker Strike Berserker (RIP 3.0)

I'm loving this build so far, but I was just curious exactly what I should be looking for on the other jewels. I understand the attack speed, but for the damage or other things, would I be looking at fire damage % or? I'm not quite sure, so any help would be appreciated. Thanks again for this awesome build!

Hey love the build i don't like Marauder tho so i made a Ranger version copying your build its pretty good i can do up to 29k dps with molten strike im only at lvl 68 working on getting more heath and i should be fine its pretty tanky so far to fast to get hit.
