Randarts not having anything but melee bonus

[Sphara]

Now, I've probably mentioned this before. It's of course a big disappointment, because more often than not, it is just as useless than a cursed or aggravating artifact. Unless found on somewhere like D4.

But my Q is that how common are these? I just had a hobbit priest game where I got TWO of these in a same game. Melee weapons, no properties, no curses, just +acc and +dam. I know it must be challenging to balance out random artifacts, but is it possible to remove this kind crap from randart game for the upcoming version?
