I have been fooling around on my priest alot lately and was thinking about some of the possible changes coming. The thing that came to my mind was to make Shadow more like Mistweavers. For example basically making mind flay like soothing mist, something that you channel most of the time but it would empower or make instant some of the other abilities.
Other spells would have to change too, like mind sear could become a nuke with a short cd like fire nova and be instant while channeling mind flay. Mind spike could become a filler that becomes instant when channeling mind flay that you use when there is nothing else to do and could add half a second to our dots duration. So you aren't channeling all the time Mind blast could keep its cast time and break the mind flay channel.
Maybe some kind of mechanic that mind flay would slowly gain power during the channel to encourage smart positioning but not enough to totally punish you if you have to move. Mind flay could also come with a slight down side of causing a low amount of constant damage that also builds up to go with the insanity and void theme.With this increase the duration of mind flay to 8 or 10 seconds. To offset the damage Vampiric touch could be given some of its leech back. The leech could be capped so that multiple applications don't become problematic in pvp. Like it can't give back more than double the health damage that mind flay is causing no matter how many applications but that just one application will more or less keep your health stable with mind flay.
They have been talking about removing shadow orbs so I don't have any great ideas with devouring plague. Maybe make it a cd that when activated it tracks all the damage you do in a 10 second window then does it again over a 10 second period with whatever cd would be appropriate.
So what do you all think?
