Such bhop is impossible nowadays without a script.
Hopped my share at speed 600 myself on the EH servers with a 10dollar mouse. And Ive seen others do 700-800. Phoon didnt du much more then 800, so maybe bhop got harder and less consistent, I couldnt know I havent been in CSS 4 years ago, but its certainly not ruined. The hitboxes are good enough, if you aim correctly you will hit. If the other guy thinks he has ducked behind a wall half a second ago and still gets hit, thats a different story. I dont see a problem in the hitboxes when the Hitboxes and the model appearing on the screen are one and the same.
Im not complaining about oranges or bananas whatever. Im saying the hitboxes got ruined over the weekend for whatever reason. Which means, they were playable before. Which means somebody should fucking fix it so they are as good as they were couple days ago. Saturday I couldnt hit shit, and ive checked the demos and indeed the problem lies with THE HITBOXES LAGGING SEVERELY BEHIND THE MODELS. Something happened over Friday to Saturday, find out what and fix it is my request. Until then I advise everyone to aim around 1/50th second behind the zombi. A zomb moves 7metres per second, in 1/50th second is moves almost a heads length.
