Okay. Um.
Witch Hunter, I assume you’re going Shadow Strike and Default Attacks for the WPS? And Poison? That’s my best guess. Because of that, I’d have to say that Solael’s isn’t giving you much at all. I’d refurbish those points to the WPS…Probably along with all but 1 of the points in Blade Barrier. And max Night’s Chill, for the RR on Poison/Acid. Assuming, OFC, that my understanding of the build’s intent was correct.
Conjurer is clearer, Vit Savagery. In which case, I’d dump the Brute Force line, and shove it into Vulnerability, and Savagery’s line. You might also want to compare Wendigo Totem to Sigil of Consumption. It’s mostly a preference thing, either work just fine IMO.
The Witchblade… Cadence-ish? Not sure. One point in Cadence, none in the modifiers. Yours builds are very spread out for some reason, just bits and pieces of points in things. If you’re going Vit/Chaos Cadence, dump the WPS from Soldier, Decorated Soldier, and Fighting Spirit. Shove the points instead into maxing Cadence’s entire line. It’s 100% worth trying to hit max ultimate ranks on each piece of Cadence. And just one point in Warcry is a pretty small radius compared to its max, feels pretty bad IMO. But that’s a matter of preference.
For the Pyromancer, Chaos Fire Strike? If it is, I’d drop Curse of Frailty entirely. It’s just not worth it, since only half your damage will be helped by it, and you aren’t using the defensive portion. Shove them into anything you’ve already got, you’ve got all the right things already.
I have NO idea what you’re doing with the Warlock. Presumably something involving Chaos. IDK. I’d suggest, generally, dropping to one point in Mirror and Arcane Will. That’s about all I CAN suggest though, as I’ve no idea what attack you’re trying to use. Presumably some granted skill, I guess.
That’s just my opinion, working with limited information. If it helped, yay, if not… Well, just ignore me then.
