How To Nerf Plasma Gun

What I would dream about PG:

And my conclusion:

They won’t nerf Ogryn. So Zealot has to be buffed at Ogryn level. Veteran will need also a buff. Psyker should get then a little nerf. Psyker should remain strong on damages, but not so much.
However, a psyker that remain a rock in middle of the battle, use the peril to deal high damages, removes threats fast and regenerate toughness if really they need it. Nerfing it too much would kill the class. So, peril generation should not be tweaked. Damages of staff are not really too strong. A gun psyker deal also insane damages.
I really don’t know the correct answer. I don’t play psyker, I really don’t like it. But, I am sure this is not the staff damages.
I would suspect, maybe, soulblaze. But not sure there is not other things too strong in their tree.

For zealot, I think that one of the most powerful interaction is until death and holy revenant. I guess zealot will get a rework. I know they don’t care of what we can think… but my opinion is that it should be something behind martyrdom keystone. These talents are needed for this keystone, but really a must have for any zealot, because there is nothing better than these 2 talents, and you don’t waste your points by spending 2 points here.
