I don’t see what’s wrong with complaining - if anything, it leads to a better metagame if we complain about things that are truly problematic or even things that we may see as problematic.
The thing is the complaints become very derailing because several of them include topics that simply aren't garnering much discussion even when they or other users try to bring them up multiple times. After a point it feels less like trying to introduce/bring up the topic than insist it be talked.
Yes! Save Gen 9! Unite against Tera!
Gliscor and Garganacl are cancerous. The tier is better off without them. Zama is a clown and people are catching on. Gholdengo is a useful mon with an unhealthy ability (it should not be able to block Defog). We can blame Gamefreak for Gholdengo.. after we evict it from the tier.
Only way to save this tier is to make moves. All the mons that perpetuate toxicity and extreme matchupiness (Volc I’m looking at you too) should be dealt with.
In this post for example, while Gargancl was on a relatively recent survey (albeit at low support numbers coming back), the majority of the other Pokemon brought up (Zama, Gliscor, Gholdengo, even Volc to a degree) were not subjects of discussion with the council to appear, didn't have particularly noteworthy write-in representation, and/or were barely generating serious discussion in the Meta talk threads (Gholdengo came up but ultimately was shot down as significant even among detractors like myself).
Well, we can predict that cancerous Gliscor will be suspected again once it rises to the top of the suspect list. Garg falls into the same category, but is just even further down the list.
I love how people act like adding 10 or so obviously broken mons to the tier somehow means shit that was broken in DLC1 is suddenly less broken. I’m just identifying what will pop up six months from now.
Gliscor and Garganacl were topics being brought up as if inevitable months ago in December, and 3 months later neither has really borne out this prediction given we have gone through 3 Suspects, 1 ban, and neither Pokemon is doing the stuff they did (or in Garg's case, were afraid they would do) in prior versions of the Meta.
The Tera topic is probably the most significant case of this: Terastalization has shown up on multiple recent surveys and struggled to demonstrate that the current playerbase is hungry for action or a ban on it overall. At the same time, RL has a history of very frequently bringing up Tera as a mechanic to be addressed even when the topic of discussion was deep into something else and the Tera comments were routinely ignored/briefly rebuffed before returning to said point.
I think the one that sticks in my head the most was a DLC1 discussion concerning Gholdengo (can be found in the archived thread if you search for Posts made by me and that include "RaikouLover" since I quote-replied to several of their posts), in which I bring up among other points
And if anyone brings up prioritizing Tera again or such: Gholdengo is a fundamentally uncompetitive Pokemon by its base kit without the mechanic for match-up flips, and if you want action against Tera, THOSE are the kind of Pokemon that need to go first to give a proper view of what the Meta is like with "only" Pokemon broken by Tera left to juggle.
Literally saying that whether or not Tera is unbalanced, I did not consider it relevant to the Gholdengo discussion because I found the mon, at the time of DLC1 meta, uncompetitive regardless of using the mechanic. RL in the following page is replying to other users with sarcastic comments about how Tera is "skillful" or that he's just saying things that don't make people feel "warm and fuzzy," which I later point out as not helping their point in a different reply, relatively unrelated to my post (this part isn't an accusation, others were discussing different matters and mine was last on its page so probably just didn't catch anyone's interest).
At THIS point they reply to ask what's wrong with them pointing out Tera is used by some mons people complain about such as Dragonite and Manaphy, accuse others of "name-calling" when saying not to discuss Tera, and then tangentially bringing up Gholdengo ("As for Gholdengo") at the end of the comment in reference to it using Tera Ghost to stuff Tusk and Treads harder. This essentially interjects my until-then unrelated Gholdengo post to make another "Tera is a bad thing" comment despite me arguing in the post itself "Gholdengo is not healthy with or without Tera, and in fact should be dealt with first if wanting to make a case Tera creates a negative meta," which gives an air of ignoring my point because they can't help themselves to deride Tera again, or misunderstanding what I was even arguing about Gholdengo throughout the entire post.
These are my experiences that reflect a pattern I think is consistent with what other annoyances are being expressed. There comes a point where the complaints cease to further their point and make people less receptive to it if anything. That said I also use the term "complaint" in a more derisive manner, because this is just saying things are bad over and over when told multiple times things aren't happening, rather than elaborating on the point or perhaps turning discussion to the actual topics.
And this is a completely subjective point, but the "Save Gen 9! Unite against Tera!" stuff is just not a very entertaining bit. It reminds me of another user making all these points about the Council as "The OU Monarchy" and such that similarly derailed topics and added little to present discussions for the sake of trying to play a part in some narrative that clearly wasn't happening.
