From what I remember of their excuses/reasons why, advanced weapons were removed because not a lot of people got to that level in the first place, they were clunky and had attributes that didn't fit with the vision of current leadership, and (speculation) encouraged twinky behavior because "I really want an advanced weapon".
Frankly, as someone who had advanced weapons numerous times, each time the big struggle was more FINDING a weapon. I had to special order knives from Salarr once, but then someone checked into why I even had knife weapons and they didn't like my twinky behavior. That character never once killed anyone, or as aggressive in any way.
