Question!

Your looking at a long time of mephbotting if you do a mf sorc. Pindle is okay but I have yet to try pit yet for drops. You could make a Hammerdin but some of the cost to get his nessessary items to do good. Suggestion: Try build a decent mf sorc (not perf) and a hammerdin for pits (or psnnecro if you wish). If the hammerdin doesn't quite work out then at least you have a good sorc for stardard mf runs and you might get lucky with meph drops. At a lower mf % he'll still have a good chance of droping occy's and lidless's that you could use in bundle trades to get the stuff you need for hammerdin.

Make a hammerdin with some pimp gear, and find a working clean d2jsp. Run the baal bot script and mf baal. YOu gain massive levels + mfing at the same time. Just gear him up and put stats/skills just like a pvp hammerdin. Kill two birds with one stone.
