It feels like a good melee can beat me on my shadow priest almost every time, but against casters I feel fine. I think if Surge of Darkness procc'd more and we took it over insanity then Melee wouldn't be as much of an issue either, but right now insanity is just way better and it's hard to get a cast off while a melee is training you. Leaving shadowform to heal is extremely risky as well, if they connect and stun you or something then you're as good as dead. Losing physic scream really sucks, but I take void tendrils over it since fear can be removed so much easier. It's weird trying to get used to pre-hard casting PoM before you go into a fight, as I would never cast it over flash heal right now if I am trying to recover in a fight. I'm playing Haste>=Multi>Crit>Vers>Mastery and using AS
