Actualy, Inquisitor worked very well with sword and shield. I had very high physical and magical resistances as well as the ability to dish out high damage to physical armor and access to some very good cc's (criple,knockdown,decaying touch, shakles of pain for zombies to execute milk combo).
Magical weapons are of so little use for the warfare and necromancer combo it's actualy pathetic to even think that there might have been some higher purpose behind this preset. Maybe there was 1 back in the day when Necromancer didn't check vs physical armor,but this is no longer the case.
Feel free to have a go over my companion review series to see how good my results were with studying the Inquisitor preset:
