Basically if you aren't in the top 15- 20% ( possibly even less IDK)of players in this game , you, your thoughts, opinions, and experiences can all fuck right off, you do not matter. That's just splendid.
I've been playing this stupid child's game since Red and Blue were banned from elementary school recess. I've been lurking at Smogon since 2007 and in the entire time I've been around I have noticed one thing consistent between generations, and that thing is bad players are really, REALLY bad and should go nowhere near any sort of tiering decisions unless they can actively demonstrate that they are able to play at a high enough level and that they understand the current meta. You say top 15-20% but globally counting all online Pokemon players I'd estimate that only the top 1% go anywhere near Smogon tiering decisions.
Pokemon is very odd among competitive games. Most games have a single player aspect and once you complete that you generally will be competent enough to enter PVP at least at the lowest level. Starcraft campaign teaches you resource management, unit types, and base building. Call of Duty single player teaches you the shooty shoot. Play literally any shooter and you can hop on Overwatch and play without any prior practice besides the 5 minute tutorial.
But Pokemon? Beat the Elite 4 and side bosses then take that team online and you will get fucking
destroyed by even the lowest ladder players. Pokemon single player teaches a lot of useless skills. HM allocation, PP vs power, coverage for types that beat you (eg Psychic on Umbreon, Bite on Espeon), items like Shell Bell vs Leftovers etc. Not just this but playing Pokemon requires ridiculous knowledge of stats and movepools as well as the enormous hurdle of learning EVs, IVs, natures, tiers, and if you're on cartridge, breeding.
Even if a player learns all that, forgets their single player bad habits, and is granted a decent competitive team it still doesn't mean that player is any good. A lot of newer players don't understand risk vs reward, win conditions, or any sort of long term planning. They just click super effective moves or predict as often as possible even when there's no reason to do so. Maybe a lower ladder player doesn't understand why Urshifu restricts team building because they don't even understand how to handle one if it's well played, but they only play against randoms at ~1300 who switch Ushifu in on Draco Meteors. Or maybe Magearna isn't explicitly overwhelming to a team that's equally weak to almost everything else. If a player doesn't have enough experience to keep themselves from losing from Dragapult then maybe they can't see how Cinderace is any worse. Then those players STILL lack the experience of meta trends and past examples from Smogon's history. How many players simply don't understand why Cinderace was banned, instead of Protean especially after a Shadow Tag ban? I guess what I'm saying is just because a player understand EVs and OU doesn't mean they have all the experience required to vote on bans or unbans.
Balancing 6v6 Pokemon is very difficult. Some Pokemon like Toxapex are not "violently" broken but would arguably make the meta more fun with its removal while some things like Dynamax are "fun" but terrible for anything resembling a competitive game. It takes a LOT of experience to understand the fallout that comes from a ban or unban. If Smogon wanted to rapid fire ban Pex + Urshifu like a lot of the community wants they could. However the meta changes almost weekly and there's going to be 100+ mons injected into this game in a few months, many of who might be broken in their own right, or might invalidate pex / urs. Newer players with less experience with the fallout of bans might just want to snap their fingers and pop pop Pex / urs are gone. But who knows, maybe that would reduce the meta to Teleport Clefable + Amoongus + Defog bird.
I'm not going to pretend I know what's best for the meta. I play this terrible game maybe 15 minutes per week and ONLY while very drunk. If anyone knows it's likely the people who play the most, which are tournament players and OU council members. The OU council could certainly be a little more proactive with communicating with the rest of Smogon, and maybe be a bit more proactive with tests and bans. Dugtrio and Magearna should have been quick banned once the problem was evident and Urshifu should have been tested. But even so the experienced players generally make the right decisions eventually.
tl;dr new players are awful, mediocre players think they're better than they really are, and even most good players require years of experience to fully understand the "economics" driving a Pokemon metagame. Leave it to the good players who can prove themselves and when voting begins just get reqs if you're super determined to make an impact.
also I've been drinking 190 proof Everclear as I type this so if I get off topic or mis-type I'm sorry.
