One of my favorites is to find people like this on my 4mages and priest and beat em down to about 10% and sheep them or mind control them and get them healed back up to full about 10-12 times before killing them. Second favorite requires specific areas of the world but bring my druid / rogue / priest / mage and use near infinite CC chains + mind control to take my sweet time walking them over to a cliff and make them bite a repair bill from a falling death.
