There are times when it shines, to be sure, but 6 seconds of self silence is counter intuitive in many ways. Especially when other classes just find that a great time to heal up or get CD's back.
We aren't getting better DoT protection and we have to deal with it. Because of that Vampiric Touch isn't as useful as I had hoped against a lot of classes. Any opponent featuring a Paladin, Priest, Rogue, Shamen, etc easily get rid of these things. In short, we can't rely on our DoT's usually. And the more of them we use, the more and more likely the opponent is going to get rid of them. I've seen a lot of people let a Pain go, but once I start stacking, it's instant dispel/purge/CoS. DoT's just aren't reliable in PvP very often.
Improved Shadowform is nice, and breaking snares is helpful. But I'm finding they are just reapplied. It would be nice if we were made snare amune during the Fade duration. But we aren't, and it makes Fading become effective when you can get a Fear off and build distance. This is valuable to be sure. The knock back resistance is cool, but the new mechanics make it less important. Where were you 2 years ago?!?!
The strengths: We have a lot of crit now (At lvl 70, I can get to around 25% with gems and gear) and it's valuable to our DPS. So because we're going to have all this crit I feel like we need to take advantage of it. We are also a dynamic class with a lot of abilities. With Spell Power taking over, our gear is going to be pretty good for healing and dpsing. So we might consider this more, since getting out of shadow to heal is more viable now.
So, this spec plays on the fact that we want to burst as well as we can. Mind Blast early and often. Holy Fire every 10 seconds. Death when we can and Mind Flay. And now since we will be critting a lot, especially easily when we heal since resilience doesn't adversely effect that, getting a free instant nuke feels valuable. That is, Surge of Light may proc a lot.
The strategy is to start in Shadow, reaping the 15% DMG and physical resistance. Get Weaving built up and when its time, burst out a free instant Smite, Holy Fire, PoM, Renew (with the renew Glyph) and Desperate Prayer if we need it. (Desperate Prayer scales INSANELY well after 70. It had incremental jumps in up to lvl 66 but at 73 it goes up something like 90%!). Renew DoT's crit and they will proc Surge of Light, giving us free nukes quickly. And MB is constantly up. The spell resistance is helpful and we play on our crit with more Holy critting and Shadow critting talented.
I just feel like Psychic Horror is a great talent and as far as we might need to go in that tree to get the best of it. We get almost all the DPS out of it and give ourselves awesome burst by more readily going to Holy Fire and getting a lot of Surge of Light procs. We don't rely on our DoT's and we can go back into shadow as needed. The big weakness is mana. But I feel like the free nukes might make up for it and not relying on going back into Shadow after heals and such might make it up.
And when we die, we are still useful as we can heal our team well enough for 15 seconds without CC, etc.
I look forward to trying this out and believe this is a dynamic build that allows the Priest freedoms to choose whats best, trick people with the Shadow form and probably the best burst potential this class has in a PvP setting, when considering we will have nice crit percentages.
