Mage/Dark Wizard Help Mage Cheap Build Lootrunning

Hi can anyone recommend a lootrunning build for lightbender/riftbender? I have tried rift walker and don't like the spell rotation, I'd rather have something simpler. I have not tried arcanist because it does not have heal unless there is a cheap/easy solution for that I would not like to burn potions. I am new so just using Morph + The Nothing. The build Need to be non-mythic for now. If the build has good health sustain for arcanist (regen/lifesteal) then I am also willing to try.

I have tried looking around but all the builds are outdated with old ability tree etc. Bonus points if most equipment I can just buy all from market as easier than doing quest/dungeon for items.
