The main reason not to use oblit IMO is that you miss out on your necrotic strikes. Even if you are doing more damage with oblit vs NS/Icy touch, the psychological advantage you get with the heal debuff from NS is too good to pass up.
So for PvP single target attacks I would look more at Icy touch/NS instead of obliterate. Come to think of it what sort of damage does glyphed chains of ice do?
