It makes sense, honestly. They have a lot of work and posts to go through, and even if you have good ideas, they can get diluted by a massive wall of text. And stating something as general as "WoD is bad" isn't helpful, because there's no problem to find or solve with that. Why is it bad, what parts are bad, what can be changed? The statement is too generalized to do anything about. Posting walls of text around problems that exist is bad because they have to sort through all the word vomit to get to the point, if there even is a point to begin with (if not, they'd have to reverse engineer the problem.. like GC was saying). It's a lot of inefficient effort and added work to go through.
Just state the problem you have with something, and be as direct and descriptive as possible about it. It can be short or long, but stick to the point or the point will be lost. A long post about a problem will likely be 75% wasted time, 25% actual point. A short, general comment would be 100% wasted time, as nothing can be done about it, there's nothing to work with.
