The thing with Enervation Guard is that when the neg levels go away, the HP lost do not come back. A mob that is at 7800/8000hp that hits you and cops 3 neg levels suffers a 15% max HP penalty and goes to 6800/6800hp. In 6 seconds the negs are gone and it is at 6800/8000. A decent effect.
Now imagine that the mob was a 150k HP orangenamed - it can go from 150k/150k to 127.5k/127.5k in one shot. 22500 damage, no save, no SR? Sounds good to me.
It's less effective late in the fight, but the temporary save reduction still matters.
