I'm not responding to everything, both because I don't want another huge wall of text, and because these few points cover most of your post.
CollaideWe don't know the impact of the whitelist / I don't want the community to shrink more
"We don't know for sure, so we should do nothing" is a terrible approach. All the information we have points to it having done nothing good. We have more information now than we did when we decided to start unbanning everything, at least. If you need more assurance that it will or won't work, you can always start polling reddit or go ask every low open player or whatever, but the information we have is enough to go off of imo.
Sure, overwatch is probably a way bigger factor, but if all that means is the whitelist's impact is negligible then we don't need to worry about "shrinking the community" from changing it. In that case we can do pretty much anything we want with it, because how much it changes the community size is a non-issue then. It's either not very significant, in which case we shouldn't worry about changing it, or pretty significant, in which case it failed horribly and we should change it asap.
CollaideSounds pretty sad, but it also sounds like the players who scored the most points won.
I'm not saying we deserved to win, and I'd be telling that story even if we ended up winning by the end of it. That's not the point, the point is that it was effective. It switched directions of a hard roll because it was just so different than anything we'd encountered before, not by them playing smarter or fragging harder but by doing a retard strat.
CollaideBut unlocks can unlock different ways of doing a strat, or make new strats (eg. soldier backpacks)
I agree, and for that reason I'd like to see them included (tentatively, because I'm not sure if those strats are actually fun and non-bull, so I'd go with more experienced players' opinions though I'm not against the idea). What do you think I've been arguing, "if it's not gunboats it's banned"?
CollaideNot necessarily, because the majority might not realise what benefits the game as whole the most. Theoretically, they could just not be concerned about this at all, but that's their choice.
I'm just saying, the only times I can remember the community being wrong about balance is when problems get exaggerated, but those same problems do still exist within the game to some degree more than they benefit the game. And I don't think it's really a problem to work off that since how big the issue is might be off, but there's still an issue with them. We, as a community, tend to be pretty good at this stuff. You're free to provide counter examples though.
