And then DoTs, while is Dispersion, those DoTs will practically do no damage and you get healed for 36% of your health. Sure you'll have those DoTs on you when you come out of it, but you'll have 36% more health and mana to counter it.
What if you cast Renew and summon your Shadowfiend just before you activate Dispersion? Add the healing from Vampiric Embrace (But you can't attack while in Dispersion; Shadow Word: Pain and Vampiric Touch deal damage) and replenishing mana from Vampiric Touch to that. How much health and mana will you have gained in the end?
Cloak of Shadows gives you a 90% chance to resist all spells, yes. But they can still be hit by a PoM Pyro for 6k. While in Dispersions, it doesn't matter how much damage is dealt to you, it will always be only 10% you actually receive. Like I said, an entire AV raid can damage you and you can survive it.
PS. You started about DoTs, in other words, Warlocks. How about this for Shadowpriest versus Warlock: Warlocks are getting Shadow Ward, which absorbs 3300 Shadow damage. Do you think you would stand a chance against that if you didn't have Dispersion, but a lame talent that increases the amount of health and mana you gain from Vampiric Embrace and Vampiric Touch? Dispersion gives you that extra time you need to take out your opponents.
