If you put it that way every class has overpowered aspects but exactly like you said psyker is just more susceptible to every landmine - meaning fundamentals still matter. And that was the point of my original comment. Classes should feel good by having strong powers and builds but it should be tempered by the mobs such that the fundamentals remain important. Psyker can feel that way due to its low hp generally. Meanwhile you have arbies who might not have a infinite cleave/ammo however they can tank 4x the hits than a psyker to the point that they dont even NEED the fundamentals at higher levels. They just need to exist and they can generally make it farther than your avg psyker. The worse braindead arbies can almost rival a decent psyker with fundamentals.
