Dont waste time chasing full sets for psionic resistance, you are completely gimping your damage by not putting damage procs in your attacks, a dead enemy cannot fight back,
Also Impervium Armour 6% is not unique and like a LOTG you can slot 5 of them across a build. Do that instead if you want some psi resist. use the slots saved to get some damage procs in there.
Pick up cross punch, because that gives you a small recharge boost and is a great space for armageddon %fire, FotG %-res and FFB % +recharge
GLowing Touch isn't going to do much for you, you can drop that tbh. You might also consider tactics, because the added +tohit means you dont need to slot so much accuracy in your attacks and can therefore boost your damage more with procs.
Impervious Skin unique is pointless
Panacea proc needs to be in health not reform essence
swap regenerative tissue for miracle +recovery
You should aim for 1 Achilles' Heel proc in your rotation.
I would pull slots from Inner Light and potentially photon seekers.
You could also consider not slotting any KB-KD in your single target rotation attacks and pick up the teleport pool for combat tp, then if KB does occur you can instantly port to them to continue, just an idea.
Hope this helps, look forward to seeing your next iteration ❤️
