This is very annoying and frustrating for actual players that play the game especially when hackers with kill aura use them. Most people if not all would support removing knockback sticks from Op PvP. If you are interested in this be sure to check out the poll below.
No support it’s op pvp, even though some hacker might use it, others might use it for strategies like to get someone away so they can /pv to get a new set of armor or something else.
I am (or was) a long time player of OP and I know they can be very annoying, but not that many people use them and they can be very strategic. They also make OP PvP unique, and uniqueness is something this server doesn't really have, and they're a classic. No support, sorry.
Please use the official KitPvP/OPPvP thread to make a suggestion for the upcoming OP PvP release. We will not be making major modifications to the legacy gamemode and will only be considering suggestions for the legacy gamemode that involve patching bugs. https://www.mineverse.com/threads/official-kitpvp-oppvp-suggestions.142429/
