yes lich took a hit( almost unnoticeable for me). but necros have ben taking hits for a long long time you have to adjust your play style and hope SoE balances waht they took out some other way be it equipment what ever. the fabled necro gear has a life tap reduced mana consumption ability and it really had no use for necros but now it does 
. same with the tainted heals and new sta line basicly soe breaks the mechanisims and makes it so you need the new gear/AA to return to a balanced state. if you plan to continue playing a summoner for any given time you wll have to learn to adjust to all these changes.
