But if I was running a full physical party, I wouldn't use Necromancer as one of the main schools. Necromancer direct damage skills scale with Intelligence and while Warfare scales with intelligence as well while using a staff, the basic attacks deal magic damage (the warfare skills too iirc) and there are very few, very situational Necromancy spells to begin with... I'd only use necromancy for support and Bloodstorm/Grasp of the Starved.
You don't need the basic attack when you can use the very powerful shield one
Add to that all the Necro physical spells and that's simply fantastic!
My Necro is the tankiest character I have, thanks to her shield and its protection spell, Forteress & Bone Cage. Imagine the damage when using all this in addition to Explosive Armor!!!
Yes it can be situational, but it was not it would be OP which is not fun
