IMO, I think the Psyker needs a complete over haul.
Something I would like to see.
Psyker restricted to staff (come back to this later) and pistols only for ranged weapons.
All staffs should be removed from the game, and replaced with staff. Staff doesn’t have any attacks, but is used to channel the powers from the Psykers selected path.
Selected paths choose the type of Psykic power they use.
These should be unique and different from everything else. So inferno would go as we already have a flamer.
I would go for
Electro - high damage, maybe stun if you pick the skills
Ice - that does damage, but can slow enemies, which would work well, with new tough enemies with the fixed armour issues
Mental - Brain burst, maybe mind control, making some enemies attack other enemies, or stun blast that temporarily stuns enemies caught in a blast, but does almost no damage or something.
The staffs primary attack should match the secondary attacks type. So an ice path with havecan ice based primary attack and secondary attack.
Psykers need to be squishy.
Force swords need act like normal swords, unless charged, if they want to do massive damage against armoured targets, then they need massive peril costs that prevents them spamming the attack.
Same for guns, no benefit from warp attacks, unless they actually charge the shot.
Only way to remove peril is through quelling, which is done by the player, but skill can slow peril generation.
Blitz come in three forms, damage, control, support, that match the chosen psykic path of electricity, Ice, and mind.
I am on my phone, but the is the general jist of what I would have done.
You build your powers and skills through the skills tree and staffs are only a conduit for your specific build.
They should be powerful, but squishy and need a lot of protection.
