The worst thing about the current build is that you have to lose damage to get core defensive abilities. Why not move all those utility talents over to the Priest tree and swap with all the shadow damage picks. As it is I’m not picking silence, dispersion, psychic horror or vampiric embrace in favour of picking more damage talents.
The shadow tree overall is a mess, things linked that have no gameplay connection at all while more logical connections are on the other side of the tree (or even the base priest tree instead).
Shadowflame prism should not be a 100% lock for the spec (by being alone on the base priest tree it certainly is). SFP for me at least is a massive pain to play with, you overcap insanity and can’t do anything else during the shadowfiend duration, on live it’s actually better to keep void bolt on cd just to spam mb’s and sw:d’s more. SFP should be somewhere on the bottom left of the shadow tree.
Just delete StM already, if it somehow is viable it will just get nerfed again.
Void Torrent seems a little outdated, especially if SFP is going to be a permanent feature it just seems out of place (the damage is also pretty lackluster), maybe change the cd to 45sec and combine it’s effects with Damnation + increase the damage of the channel. It would make it a great opener cast again, because at the moment I’m not sure it beats out getting the SFP rotation going earlier.
There’s just way too much crap in the last tier of the tree, with the idol’s being obvious things to want to go for, you aren’t even left enough points to get halfway to the other side. I feel like you should be able to get the powerful talent and then explore towards the other side a bit (but obviously not have enough to get both sides powerful options). In the 3rd tier pretty much all of the talents other than the idols look god awful, either boring or not powerful.
Reworking the trees:
All non damaging abilities (self shields, silence, dispersion, vampiric embrace…etc) should be on the base priest tree, while all shadow damage talents should be on the Shadow tree.
Shadow Tree
First tier should be about aoe choice, move psychic link and shadow crash up here. Void Eruption should be the last talent to link to the next tier.
Second Tier left side could be more based on apparations and shadowfiend, the shadowfiend talents should go where shadowcrash is. The middle is about mind blast, shadow word: death and void bolt. Right side should be more dots and channel based.
Third tier should continue the trend from the second. The idols need changing around with Yogg-Saron swapped for N’zoth. SFP should lead into the left idol, Void Torrent leads into the right and Mindgames the bottom center.
Base Tree
Removing all the mandatory shadow damage picks opens up the tree for some interesting choices, I won’t go through every tier but Dispersion and Vamp Embrace should be the final options at the bottom right rows.
Overall this looks like a very very early draft and I’m at least glad its out there early to get this kind of feedback because it definitely needs it.
