I know it’s bugged right now, but this actually introduced a really nice gameplay loop to psyker: an elite-focused caster, which can be implemented by making Surge actually consume Psionics stacks. a
Allowing Psyker to one/two shot elites(probably should three shot Ogryns) IF player doesnt waste stacks on anything but them. Boss damage will still suck, horde damage is already nerfed.
Psykers might get a nice, permanent playstyle out of this issue.
If the interaction were to stay, would there be any reason for Surge staff users to pick any other keystone? I haven’t seen the interaction in game just yet, but it sounds like it’d be a near-mandatory combination (especially with 100% proc on elite kill).
