How is wizardry in sjWH40K? Is games Wokeshop too inflicted with balance cultism?
In fluff they are extremely dangerous, to the point that the Imperium basically enslaves them and has several organizations dedicated to keeping them in check.
Think the mutants from marvel shit, except they're all Magneto, Doctor Strange or Scarlett Witch or some shit. Also there's a good chance that they'll get possessed and become a living portal for demons and other horrors of the warp, hence why they are so heavily regulated.
In game they are pretty damn useful. The factions that don't have access to psychic powers are pretty much at a disadvantage, as they lose out on an entire phase and anti-psy abilities are a joke. Even Necrons, who are supposed to be experts at countering psykers, have shitty defenses. They do get C'tan, which are something of an alternative to psykers, but they tend to be more expensive than most psykers, can't counter psychic powers themselves and have no buffing abilities.
Most psychic powers inflict mortal wounds which outright ignore most defenses, and psychic buffs are great force multipliers. If your army has access to a psyker, you should try to get at least one because of the utility they provide.
Keep in mind though there's a chance that the Psyker takes damage after failing a test because of Perils of the Warp.
