I believe that good manners are mandatory always and in any case, no matter what you ask.
I also realize that reworking a class or revisiting it can come to require a frightening amount of work, as you have to consider so many factors such as:
How can I make it viable?
How can I change it but at the same time make it not too different from how it was? as surely there are people who enjoy playing the current Psyker who is forced to spam Brain Burst.
and various others.
I do not expect the Psyker to be reworked immediately with this post, I think an actual rework will arrive perhaps in a few months, but I am confident that Fatshark will, as during this pre-order Beta they are showing that they listen to the community in various ways.
For example a couple of weeks ago i made a post in which I explained how the revive and other interactions in the game need animations and that the fastest way to solve the matter was to add a small switch that leads to the 3rd person when starting these actions.
they listened and today we have the revives and others 3rd person animations instead of the 1st person character totally absent of animations.
