The bigger problem isn’t that Soulblaze kills the enemies other players are fighting: it’s that the Classes have no real defined roles, and every class is currently designed to hunt Elites and Specials, which means you’re forced to compete for kills against those targets to get your conditional buffs. Because everyone’s conditional power is tied to targeting and/or terminating Elites, Specials, and Monstrosities, ever game will devolve into a race for the bottom. This is what causes people to push further out, reducing team play and cohesion. There are so many builds in the game that will just turn off the experience for other builds since those builds can’t keep up w/ the rate at which the other build can secure targets. This isn’t unique to Psyker unfortunately, and will persist so long as the triggers for power in darktide are tied to the tier of units and not armor of units. If Psykers were specifically built to gain power from fighting and/or killing, say, unarmored enemies, and you gained power from fighting maniacs, then the only time you would go out of your way to target something else is when there’s nothing else to fight or you are trying to help your allies.
