This is a few changes that will make the shadow tree more or less perfect in my eyes
Move Mindsear up to be part of the MF node - It’s two sides of the same coin, don’t make us pay double
Move around Fortress of the Mind and Death and Madness - It makes more sense to have our “mass” death placed alongside our AOE, and MF/MB buffs on the ST side of things
Searing Nightmare - Replace it with a standalone version of Void Eruption
Make two or all of these free nodes, Silence, Dispersion, Vampiric Embrace or Psychic Horror or at least add their secondary nodes into the primary, to make it easier to justify picking them - We’re currently the only ones that have our CC and defensive in our spec tree, so making them free will be the right way to go about it - Even with them given to us for free we won’t have enough points left over to justify the secondary nodes
Void Form - Should be a standalone instant cast
Monomania - Make it a permanent debuff applied by Mind Blast, basically make it work like Fae Guardians - This needs to happen otherwise we end up in a constant MF spam fishing for procs again
Damnation - Rework it to apply SW:P and VT to all targets within 15 yards of the main target - We really need this seeing as you devs for some reason keep locking a lot of our AOE behind VT
Surrender to Madness - Just remove the death part already and and make it a passive modifier then it’ll make a fine talent - Like it’s only the cast while moving part that’s really good about it - Maybe add an interrupt shield for PvP purposes - The choice between 10% more damage or moving while bursting, will equate to roughly the same power while bursting, but be a net loss in total, with the MF proc VB talent
Psychic Link - Move it up to Mind Sears location - will be a very easy AOE tuning knob
Shadow Crash - I don’t see why it’s still a thing, but if it is to remain, make it track the target, rather than it hitting the targeted location long after the tank has moved the enemies away
Mental Fortitude - Rework it to apply a stacking shield for 10-20% of all shadow damage or rework it to make PW:S a passive that reduces all damage taken by X% spellpower per attack. And if chosen Body and Soul becomes permanent but at a 10% penalty
Sanguine Teachings sounds more like a flat leech buff like 10-20% and it should be a 2 point talent - Or leave it as is and implement one of my above mentioned ideas
Abyssal Knowledge, make it a 2 point talent as well
Separate AOE and ST talents better, as they are right now it looks like a hot mess
And just to remove bloat from the tree, add Shadowy Apparitions to our mastery. With damage and proc chance increased based on mastery %. And can be proc’ed by any shadow damage - This will remove 4 pure bloat talents. Or remove at least 2 of them, and let the other 2 buff it after mastery
While on the topic of mastery, remove DP from it and let it stack a bit faster - This will also make us feel like we’re not missing out on as much damage in AOE - Or buff our over all damage a bit and just go with the above mentioned idea instead of keeping the three part mastery
As for the class tree
I only really have one problem, and that’s Shadowflame Prism still being target locked at 5 targets - In a world of uncapped AOE this cap can’t stand!
And a suggestion. Make Leap of Faith a choice node and add instant cast Door of Shadows as the second choice - Yes IK everybody have access to that, but thematically it fits priests better especially shadow priests
