Review

Focus on releasing w after every hit, and pressing it down again. Another timing is to hit your opponent, then release w right before you get the next hit.

One important thing to note, is the damage cooldown. Players can only take damage once every 0.50 seconds. Ping can mess this up slightly.

Only blockhit after first getting a hit on your opponent. Blockhitting is more useful in tight spaces where you can't get comboed.

Try not to jump too much in pvp (as a beginner). You take more kb while you are in the air. This can cause you to get comboed more easily.

Make sure to aim around the neck. Aiming perfectly in the center of the head is inefficient because when you get hit, you will get lifted into the air, and it will be difficult to look down at just the right timing.

If you have trouble aiming, you can practice by queing duels with speed, like op duels, and nodebuffs (on minemen club, not hypixel). Increasing your fov to quake pro or increasing your sensitivity temporary may help.

The easiest way to gain more "awareness" in games, is to just increase your fov. My fov is on quake pro (100 after dynamic adjustment).
