Awsome, have fun having a 1k dmg melee attack or ww. Zon's don't have enough res to begin with to be any problem. Necros can go full sorb but itll fuck up their build, and make them slow as fuck. Also note that the shields i Use come with a +xx to resists as it is. Also remember that the paladin has a charge attack. He can blindly charge through all that shit while any other char class has to tele. Sure any other class could negate the sorcs attack, but very few could catch up to them.

As a side note, I rarely have to use this setup. Usually a raven , snowclash and max res will do.
