Don’t worry, some psyker OTP will come to tell you how you are wrong, the class is perfectly fine but you don’t understand how to play it, then will tell you how it’s only somewhat viable with a very specific build and a weapon with a particular set of blessings.
Then the rest of the comments will laugh at the absolute clown and the post will fall into oblivion while we wait for a psyker buff/rework.
Have fun.
