which sorc is best to start havent played in a while

Probably a Warlock.

If you save up enough and find a Shacko you can try a foh pangolian.

PM Proint for build ideas and theory crafting needs.

Blizzard if you want to farm as many areas as possible on a budget

Fire if you are okay with target farming

Frozen orb with a secondary fire skill is my favorite for a playthrough but it sucks for farming the clear speed is slow.

blizzard for general mf on a budget and it's not even close
