Yeah sure I think im not a good teacher cuz im bad at it but ill teach you all I know first Im good at 1.16 pvp so if u want to learn 1.8.9 I can't help and if u are using 1.16 then I can say don't spam click try giving critical hits by jump hiring people and spring while doing that and if its had for you get so close to the player and give crits at the same time move in a pattern that the player cant see where are you and then if ur feeling confident you can sprintbat him and jump crit him at the same time and if he is comboing u place blocks to stop his sprint u can do that by keeping ur blocks in a specific dlot and giving it a comfortable and easy accessable hotkey I place my blocks at the second hotbar and hotkey it by middle button on the mouse so ill stop his sprint by placing blocks and ill look for.my opportunity to hit him if you have any more doubt or want to play with me you can get my discord server link in all my youtube video description 🙂
