KB Sync plugin should be revisited as many of it's issues have been fixed
The problem is that it requires and updates since the public KB Sync plugin is not up to par and has some inaccuracies when dealing with players with
The current problem with the public KB Sync plugin is that its not really accurate when it comes to dealing with players with unstable ping resulting in awkward kb, although it has gotten better I'd hope. It needs testing
A lot of servers such as MMC, Stray, Cat PvP, PvP Club, etc have their own implementations of KB Sync, in all honesty they are really all the same in practice and only differ in niche scenarios where the player's ping is massively unstable.
I believe the current KB Sync plugin can be configured well to be fit for Loka, however it would need feedback from prominent duels players such as myself and
@CASELOAD to ensure it is configured properly. (I don't really trust Cryptite gets it right on the first try without help from pvpers as he himself does not pvp)
Truthfully, a move to KB Sync will be seen as unpopular, as it makes it so players with high ping can get attacked faster resulting in them being able to be combo'd, it will be a nerf for high ping players.
Another thing is that it is a scapegoat, any issue with the knockback will automatically be blamed on the kb sync, regardless if it's actually related or not. (Spoiler Alert: on Stray we'd have people complaining about the KB Sync and the plugin wasn't even on)
For a compromise since people will complain hard I think the offset should be 100ms/2 ticks, all servers have it on 50ms/1 tick so laggers are still buffed compared to other servers.
