Yes please tell me more, about how getting snapped back to something you dodged is not a big deal.
Because it's not something that didn't hit you, it's something that due to a combination of latency on the other person's end and possibly tickrate (latency is far more likely than tickrate though, if it's more than a fraction of a fraction of a second worth of 'snapback' it's 100% latency). Like, if they flashbang you when you're there on their screen and the server agrees 'yeah that wasn't bullshit, even though your ping is high fam' then you're going to be stunned. If that person had 0 ping and 1000 tickrate, they would've stunned you too. So the correct outcome was given.
Even that video that keeps getting posted is a dude with 700 ping, like...why the fuck would you think that's related to tickrate, if you want to show the effect of tickrate you want as close to 0 latency as possible.
20 tickrate is an AT MOST (like, if the action occured the next millisecond after the tick happened) like having 50 ms between when an event occurs and when your client receives it. on average 25 ms.
Someone with a 30 ms ping is actively making you feel like you got bullshitted more than the tickrate is, that's how inconsequential it is (Also, tickrate wouldn't have changed what happened to you, it just would've changed how many miliseconds it takes before your client realizes it happened. If you get shot you still would've gotten shot, you just would've not been behind the corner yet on your end).
The fact that people bring up tickrate that probably have never even heard the term until this '20 tickrate lolol' bullshit started is telling. The tickrate has a near 0 effect on your ability to actually do anything in the game, it occasionally makes you go 'bullshit I was behind a wall' or something, but A) latency does that VASTLY more noticeably. B) Whether you 'think' you were behind a corner or not is pretty irrelevant when the server is deciding what actually is happening, like it has no impact on the results of the actions taking place, just the perception of them. It might as well be the latency equivilent of 'if a tree falls in the woods'. The classic "I got shot behind the corner" or "hooked behind the corner" would have 100% the same outcome whether the tickrate was 1000 or 5.
