Apologies for long post ahead:
I think overall this seems like more of a communication/PR problem than anything else.
There are lots of people who are misinformed (or deliberately acting in bad faith) when talking about this topic, but the poster of this video in the yt comments seems to at least be somewhat reasonable and open to change, and I think if they were to have a genuine respectful dialogue with prem-level players they would at least understand things more.
People keep saying that they are spreading bad faith takes on purpose but I actually disagree with this. Having been in the fucking trenches for too long on tf2 reddits and youtube comments because I want to kill myself or something, I think comp players can be somewhat myopic when they consider how obvious the reasoning behind many changes in competitive are.
The video is an example of this issue but I'll provide an example of my own (because I'm more familiar with it); loch was recently banned in NA highlander. If you're not in an invite highlander circlejerk, or you have no connection to invite players (which I would hazard to guess is actually most people playing), what are your avenues to actually learning the reasoning behind wanting such a ban?
- Weapon was barely used at all during the season until the end (and probably even less so in lower divs I would guess), so it's not like you would see firsthand its problems
- Lower divs are worse at the game and thus worse at exploiting the weapon
- RGL forums are giga fucking dead so who knows what ppl are thinking (save the thread on loch, I'll come back to this)
- It's come up a couple of times in the main channel of the league discord, the channel that is dead like half the time and the other half the time it's talking about random shit, so very easy to miss.
- You can watch like maybe 2 casted matches last season that used it primarily, and with POV cam's + the cam not always being on the demo it's hard to get a sense of just how much the weapon is warping how ppl play. Plus how would you be able to tell between this weapon is changing how ppl play vs. this is just how invite teams play?
Now all of a sudden you get a survey question about whether or not to ban the loch. You have no reference point for why people want it gone, but obviously something must have happened, some meta shift. I don't think it's entirely unreasonable to assume that people are just being mad because they fail to adapt. Here's an example of such a post, and you can see the replies and that they later change their mind after hearing the reasoning. Is it annoying that people default to "comp players want thing banned = they are bad and salty cause they lost to it"? Sure, but in the absence of information available to these players I don't think it's a crazy conclusion to reach.
Ironically I think some comp players need to touch grass and take a step back for a second. It's really quite difficult for ppl who don't go out of their way to interact with good players to get a sense of what they're thinking. So ETF2L cringing it up by putting the wrong ban reasons (2 shotting sentries lol) actually can have a pretty significant impact on things. Proper articulation of why things are unfun or broken goes a long way; I know because I've been around that "unfun" roughly translates to either "rewards excessively defensive gameplay" or "incredibly rng and luck based" or "why are we giving the best class in the game something that makes it even better" or whatever, but others may not and that's perfectly reasonable.
