I agree the systems needs to be improved. Over a couple of houndred of ratings I received only one was truly helpful and helped me to improve my profile. And it was a 4 stars review.
I think they are multiple reason why the ratings are so poorly described.
One is most certainly the language barrier. The main language used on MW is obviously English. And of course not every can speak fluently English.
The second is probably the skills level. New first printer users who use only the Handy App. Don’t have the experience nor the vocabulary to explain or identify the issue.
That’s why I think most of them just tick a box with a generic explanation like bed adhesion. Or more frustrating for us : other issue ^^`
I think it would be better if sending a image was mandatory. And the description optional. A picture worth’s thousands words (in any languages).
And it would be nice to have some meta data attached to the rating like: slicer or handy app, printer model, build plate type, nozzle size, filament profile used (k factor even if it’s possible ^^). Those extra information would automatically filled based on the print history. No extra work for the user.
That would solve the majority of the issues IMHO
