The source i read the tier bonuses for said that it extends not refreshes. Extends VT and SWP to deal dmg one more time. I agree the tier bonuses for Priests are aimed at our weakest source of dmg which is rediculous. We need something that will help use burst out dmg on nuke phases or at Bloodlust/Hero phases. Every other class has some sort of straight dmg increase button. Why not have 4 piece bonus add dmg increase to Vampiric embrace? Would allow better usage of the spell instead of holding onto it for phases where healers need the extra heals.
I dunno, Vampiric Embrace is one of the few healing cooldowns available to dps specs. It's pretty handy in periods of high damage, I use it to help out the healers all the time.
We could definitely use a dps cooldown. Power Infusion is the closest thing we have, but right now, it can't compete with Twist of Fate or Divine Insight.
Personally, I think that Divine Insight should be baseline (for the Shadow portion), the extra Shadow Orbs are too good to pass up. In Beta, for a short time, it actually was baseline for Shadow and the talent let Mind Flay stack a buff that increased the damage of our next Mind Blast per tick of Mind Flay, up to 10 stacks. That was an interesting talent, I liked it a lot. But if they insist on keeping DI the way it is, then Power Infusion needs a buff. Maybe it can grant 3 Shadow Orbs on use while in Shadowform? That would give you a guaranteed Devouring Plague to benefit from the big haste buff, that would make it a better cooldown, right?
But since that's a talent, it still can't be our only cooldown. My idea for a baseline burst cd:
3 minute cooldown
The Priest unleashes a torrent of mental energy, assaulting the target for X damage per second. While the effect lasts, the Priest gains a Shadow Orb every 2 seconds. Lasts 12 seconds.
Originally, I was gonna have the cooldown let Mind Spike not consume DoTs and also generate a Shadow Orb, but I thought that this was cooler.
