You don't necessarily have to be a TOP player to judge.
For example, I wrote a lot of good articles about StarCraft, even though I was just an average player at my peak. And I wrote most of the articles after I had stopped playing competitively, meaning I wouldn't even be able to beat an average player. Yes, sometimes this led to mistakes, and I was corrected, but overall the texts were quite adequate.
But not many people can do that. And in your current state, you clearly aren't one of them (objectively speaking, no offense). That's why you're being advised to at least reach the level of an average player; maybe then your analytical skills (if you have any) will produce adequate results.
I repeat, the main thing is the right train of thought. If it's wrong, then it makes sense to look for the reasons – either you lack skill, or you lack intelligence, or something else.
Take, for example, your discussion with Stinger about morality. I don't agree with Stinger's position; in my opinion, he goes to extremes. But our disagreements are quantitative, in the assessment of the degree of influence (I believe it is higher), and not on the essence of the issue. Here, we can discuss it constructively and perhaps even come to a common opinion (even if it turns out to be multifaceted). But your position is purely wrong, and your arguments only emphasize this fact. Therefore, constructive discussion is difficult here.
Similarly, regarding entertainment value – it's good that you recognize the importance of this aspect of the game and are looking for factors that influence it. But either due to a lack of experience with this issue or due to initial bias, your conclusions turn out to be wrong, and again, your arguments only emphasize this.
I myself have analyzed and discussed this issue in relation to various computer games (and even traditional sports), so I see the flaws with the naked eye, much like an experienced musician hears obvious dissonance in a melody.
The specifics of discussing the issue of entertainment value is that there is little subjectivity here; you can't say "there's no accounting for taste," entertainment value is a perfectly objective parameter that can even be measured numerically. Therefore, the approach to opinions here is appropriate.
Here is my old article, one of the first steps in esports journalism - http://cyberfight.ru/site/columns/56/article_18911/, which discusses the entertainment value of an esports game. I just reviewed it, and of course, there's a lot of naivety and awkwardness there, but all the key factors are surprisingly accurately identified (I even praised myself). And most importantly, subsequent events have shown the correctness of this approach.
