oh wow, it's that simple. For some reason I was convinced it was A Better Barracks Perk Pack ability. Thank you very much for this investigation, I'll add it right away.

So I did some troubleshooting; started a new file with only BalanceGoldPrime++ and its dependencies installed, console'd in the psilab, and got myself a supersensory. Blend still does not appear for me. I checked my configs, and F_Blend is right there at supersensory rank 1.

On a hunch, given the perk's internal name, I enabled Extended Perk Pack by Favid, and sure enough, that solved the issue. Should be as simple a fix as adding EPP to your list of dependencies. Maybe it was a transitive dependency when you first published this mod, but it isn't now. Hope this has helped!

I did figure it may be difficult or impossible to implement, and like I said it's a quality mod in its current state. Natural probability distribution will eliminate the need for a forced deck in most cases anyway, even more so the larger your barracks gets. Forcing psi class diversity isn't about to make or break the quality of this mod.

Thank you for the comments! I'll be on the lookout for that Blend issue, but as of right now I can't possibly know what this is about.
About your suggestion - that is a great suggestion, but I'm not sure if I can enable this. After all, this mod is just configs, if Psi Overhaul V3 itself supports it, then I'll check if I can make it so, and if not, then I can't do anything about it.
Just for reference, here is my psi class distribution in my current campaign:
Mentalist - 3
Psi Tech - 2
Psitonomy - 2
Supersensory, Elementalist, Reality Warper - 1
Necromancer - 0
total 10 psionics out of 53 soldiers.

Probably-user-error aside, I've enjoyed the mod. It has an amalgamation class sort of effect where no two soldiers are alike (probably). My combat engineer necromancer stands apart from other CEs, and each supersensory soldier plays differently from others of different base classes.
Perhaps my one recommendation would be to enable some sort of forced deck functionality, or other probability-bending system. Of 20 soldiers I rolled 7 psi ops (so, as expected), but 4 of them were supersensory. If it's not already implemented, it would be nice if there was something in the backend forcing/encouraging variety, so you can expect to actually experience most of the mod's content in a given campaign.
That's just a nitpick though. This is probably my favorite psionics system in xcom 2 that I've played. Thanks for making and sharing it ♥

Bizarre. I double-checked I had the dependencies installed and enabled, and I didn't touch any configs. I wouldn't think another mod would be interfering by accident, but that must be it if all is well on your end. I'm far from an expert.

@Baked Valkyrie - I don't know, Blend appears for my soldier in the ability. I think it's from A Better Barracks. I'm not sure what the problem is but it might be on your end.

Not sure what this is about, I'm pretty sure I had blend on the soldier just fine, but I'll take a look again at some point later to verify.

My supersensory does not have blend (or any ability) at rank 2. I can't find the skill in any of the dependencies' perk lists, so an update to one of them may have removed it?

I apologize for the inconvenience may have caused you. Feel free to apply for a refund.

It must be pointed out that in the first paragraph of the Overview the author of this mod refers to themselves using a first person pronoun rather than "the author".

-1/10 literally undownloadable please fix

I do not use this class...

do u use the "wotc tank class"? disable this one fixed it...but i rly like the class

Well, if you further investigate and find out that somehow it is related to this mod, then please let me know.

yea, i have too many mods to do that, i only found out cause i just added urs,... will not bother u further, guess i just wanted it to get of my chest:D, thx

Yes, I don't know. If you can share your AML profile or mod list then I might look into mods that you have that I don't that might somehow be in effect here, but I'm pretty sure that if you just start a game with this mod and its requirements and proficiency templar, then there won't be problems with proficiency Templar...

yea, i know, thi smod doesnt even have a classdata.ini, thats what make it even more weird, the skills he gets from start u get on major rank normally with this pro templar,
possible a weird threeway modinteraction,

This is weird, since I'm using this mod with Proficiency Templars, and they work fine. It should not affect normal soldier classes in any way...

this mod is weird, with this mod on profiency templar has no focus bar, no momentum, arcwave(dont think these skills are from ur mod), exchange and raise zombies in an aoe around him, but all need focus:D, disable your mod fixed it but wth?

thanks for the help, ill see if i can get it working on my end.

it seems like the names for the abilities in LWOTC are completely different than the names for the parallel perks in LW2 perk pack. I'm not sure what's the best way to resolve it is, you can try using the LW2 perks in LWOTC, no idea if that will cause any issue, or edit the ability names in the config.
The only ability I really use from LW2 perk pack is Bastion. The name of this ability in LWOTC is just "Bastion", so you can try that. Don't forget then to edit the requirements in the Ability Prerequisite get arounder. Note that the last change will also affect other things in LWOTC.

Of course, there might be other complications, I never played with LWOTC...

if i use this with Long War of the chosen, do i need LW2 Classes perk pack? since the perks are already (AFAIK) in Long War of the chosen?

@Vanilla Autismotron

Yes, the original console commands from mod work. For the internal names of the psi classes, check the configs. I think they're just the displayed name with an Abizi prefix, so AbiziPsichologist etc.

Very cool idea! I'm definitely customizing this.

I'm guessing the forcepsigifttreeXXX or something similar command still works with these, so I can manually select the psi tree?

Good idea.

Seven colors of the rainbow that correspond to the seven psi classes introduced by this mod.

Mod preview image game is strong with this one

Certainly an interesting take. Congrats on the release.

This actually sounds really cool, and I'm surprised it hasn't been made sooner seeing how nearly everybody agrees about how psi abilities like Domination and Null lance kinda ruin the balance of the game.

Congratulations on this new release!
