No they expressly stated that it was to find one with a good base stats and upgrade it, they even said as much in their update post.
It’s also there because the chances of finding say a psyker staff is currently absolutely terrible.
While good advice i think the issue is past a certain point there is nowhere really too go with it. A lot of times 350s and 360s can work but if you already rolled a 370 with 80s in damage but dump stating something important the most you can do is try and roll something comparable with slightly better stats or a better blessing, etc.
Being real there isn’t a whole ton of content so once you tried one of every weapon your want progression wise all you got left is going the brunts route if malks or the regular store doesn’t give you anything.
This is as stated the system working as intended. Getting 53 weapons with nothing worth using on them is entirely possible in the system.
