Wondering about Necro "rotation"

[duneadx]

Hi all-
I was wondering if anyone had a "rinse and repeat" type method of spells that they use on their necros that they find most mana/hp efficient. Lets say hypothetically its a camp where you can single pull a mob your level or dark blue that is a warrior with plenty of room for fear kiting. Is this method similar at high levels as it is with low levels? Do people still let their pets eat the xp at 50+ if there is no undead available to charm?
