This has been happening to me more and more lately. If you are indeed overgeared for an instance, you are most likely keeping decent threat. As long as your DPS isn't insane, you can start working in judgement of wisdom especially now that JoL doesn't scale threat like it used to. If you still have no issues keeping threat and still need mana, use SoW as well. I first started having these issues in H VH and with those three (JoW, SoW, sanc aura) i don't have to drink between portals.
I switch kings on during bosses as well as my usual judgements and seals, and my damage output is much lower, but it gets the job done. /shrug
