This sort of thing affects pvp a lot harder and is pretty annoying. Pretty much when playing for 10 minutes. If someone who just logs in pvp's you they have a bigger advantage (knockback, out of sync sort of).

This ticket is invalid as it relates to a modified or 3rd party client, server, or launcher.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the plugin / resource pack creator.
This site is for addressing issues related to the base unmodded Minecraft; Bukkit, Forge, Optifine, or any other modded system may invalidate your ticket.
Additionally, if you have problems on servers like Hypixel or The Hive, please report it to their corresponding site. It's probably not a bug in Vanilla Minecraft.
