What was the point in taking away shotguns on psyker?

we had it during the beta. maybe it seemed too powerful but even brain burst saw a big nurf.
It was an excellent middle-range replacement for many of the longer-ranged lasguns for some kits. I don’t want this to devolve into why would you use a gun thread. I’m well aware the gun side of a Psyker is very very lackluster and could use a serious combing but there are higher-end problems for the class and that is not what this thread is about. if the answer simply is we didn’t want to fine but I hate that we had something “cool” and now we don’t.
