I have a pretty bad pc and my ping is about 15-50 sometimes while not playing any games. I check on pingtest.net But when I play minecraft I usually can get 20-300 ping. Since I play on a PVP server I usually run around chasing people and I need to get really close to them in over to hit them. Ive seen videos on youtube and when they are like 3 blocks behind someone they can still hit them and when i try I cant. I literally have to almost be inside a playing when running to be able to hit them. Thanks
