It quells nothing
the change is awful and is ruining my main class for me, it makes brain bursting bosses down maybe half as effective because instead of doing a quick quell to get 2% peril off i need to do it for over a second before being able to brain burst again, it also feels really bad because i have a high actions per minute playstyle, i beg you fatshark to revert this
if you play on PC, get the Guarantee Quell mod. It’s unfortunately the only way to retain some semblance of the prior tap-quelling mechanic, at least until FS reverts this madness.
I tried that mod and while it does provide some safety against holding quell too shortly, its’s drawbacks are the same as all the other “guarantee” mods that try to compensate for the games intrinsic latency and even worse tendency to drop/ignore inputs: you can often end up queing inputs that lock you into certain actions that became counterproductive.
Yea, it’s not a direct fix unfortunately. But I don’t know what else we can do. The disparity between quelling in normal vs Havoc is such bad game design now, it feels like the most rushed and untested nerf. The muscle memory loop that’s in my brain from hours of playtime is totally broken, making simply playing psyker in Havoc not fun at all. I also have a hard time buying that the prior interaction was a bug since it was around for 2.5 years now since Havoc started, but I probably missed reading something in the patch notes about this.
Praying this change does not get reverted 
Big E is a psyker-main, he is not listening xd
It could get reverted and then applied to the rest of the game. That’d be nice.
you aren’t allowed to enjoy playing psyker, all future nerfs should continue to ruin game mechanics
