Necro in shade are immune as we all know. It give the necro the possibility to leave the pet inside a tower or keep and go out w/o fear to die and set a groundtarget right under enemies group with no danger for himself but giving a big advantage to albs.
My sugestion is to remove the right to necro to set GT if their pet is not in view, to prevent them to go out find a campfire where a group is resting and set a GT right under them.
Class with gtaoe are unable to set the GT exactly where they want if they can't see in or out of the keep (tower) but with the necro gtaoe become really effective for the defense of a keep or tower or when all defender are in the lord room and 1 necro in shade come in set a GT in the right place and call all albs to use is GT for a maximum effect.
Sorry for my english I am not very good.
