/ping them before u do anything. Anyone with over 100 ping should be avoided unless ur confident u can get the first combo. Ill edit this post ina bit with why high ping is an insane advantage
Edit:
- speed one is 6.8 blocks/second or 1 block every 0.14 seconds.
- normal reach is 3 blocks.
- KB is 0.5-2 blocks
When u add ping into this, the delay for a player with 100 ms (0.1s of delay) plus the server delay, plus the relay back to your computer can end up 100-300ms more (0.1s + 0.1s = about 0.2 seconds delay for players with 100 ping which drastically increases for players with higher ping). With speed 1, in 0.2 seconds, youve moved (0.2 ÷ 0.14) = 1.4 blocks or about 1 and a half blocks closer.
On my 33ping screen, youre still 4 blocks away, aka unhittable. On your screen, you are now 1.5 blocks closer, at less than 3 blocks away and im within reach. You will be able to hit me from way further than what looks legit on my screen.
Note: this doesnt include hit delay but hit delay depends on a lot (hit packets send quite a bit faster so they can be ignored up to a certain level)
