My thoughts are primarily from an affliction point of view, in part because most of this thread is how it does not suit destro, which is definitely true, but it would be disingenuous if that was the only feedback coming in for Hellcaller.
Like those above me there’s some clarification issues that need addressing:
Will any ability/talent that interacts with corruption also interact with wither in the same ways (Or augmented for tuning purposes)? Specifically Seed of Corruption for aoe applications of wither and Absolute Corruption for a permanent wither dot (specifically how this might work with hatefury Rituals).
With Mark of Xavius combo’ing to apply affliction to an additional target, is there a concern we’re losing vile taint and/or it’s ability to spread agony in AoE? If so this is a tremendous step backwards, if anything we need a way to maintain agony on a group in aoe since the duration for agony and cd of Taint do not line up. Tab targeting refreshing the dot that is our only way to generate resources in an aoe group feels pretty awful in-between vile taint casts to not lose stacks. If vile taint aoe application remains this combo feels kinda superfluous but might be nice in a council style encounter I guess?
Malevolence wording is a bit murky on Rapture applying an additional stack to targets with Unstable affliction, is multiple targets with UA a thing coming back, or is this just murky wording?
I do like the addition of Malevolence in general, having a nice actual CD for affliction (since aside from dot extensions Darkglare is kind of awful with the current state of affliction) would be wonderful, and this is kinda like getting Dark Soul plus a major Wither window. My concern is that affliction has a fair bit of bloat as is, I see this cd as a solid addition, but it would be nice to trim some of the fat (seeing Siphon life on the chopping block or turned back into a passive and dots retuned for the loss of siphon’s rapture value would be lovely).
All in all, I am fond of the tree, just a lot of clarifications that need to be sorted out, and it’s difficult to say how good or bad this might be until we have an idea of what changes we can expect to affliction with 11.0. A fair few were probably expecting a large affliction rework going into WWI, and based on these talents that doesn’t seem to be the case, but certainly some minor reworks will be coming as they always do inbetween expansions, and could impact how this hero tree feels.
Finally, I can understand Destro players dislike for this hero tree based on the class fantasy with the key thing revolving around dot (even if it is simply replacing the dot they already have), and I hope something can be done there to resolve this for them, but hopefully not at the cost of sacrificing what looks like it could be a lot of fun for affliction. These are early days and feedback is here for this reason, so hopefully we can see some stuff retooled for destro to fit the spec identity better. Maybe instead of revolving around wither stacking and flaring up have it interact with Chaos Bolt and Rain of Fire in some way for them.
