I could see changing the necros undead dk, to somthing else like greater (or king, or champion, or some other prefix)zombie or skeleton or somthing (since all they are doing is wearing armor and wielding weapons) and use the name Death Knight for the other necro type class.. being a more melee class.. have chain as there max armor but being able to cast spells to boost that armor, and possible spells like the plauge shield thing would be pretty sweet, plus the normal death touch, curse, ice damage, maybe even alow them to have some summons (maybe a beast, or acolytes, corpse fiend, and/or a ghoul as a MAX) and ofcourse all the darkness fun you can handle, unlimited WC weapons.. hmmmm
