I found Eternal PvP and it is a Bedrock and Java PvP practice server made for people who want real fights.
It has clean FFA so you fight everyone with no teams and it also has competitive duels for 1v1 skill fights.
The combat is meant to feel like Java and it has custom PvP tweaks plus Java style chat and tooltips. It also uses low fire so you can see better.
It is built for sweaty practice and it focuses on smooth performance with a 40 player max to avoid lag chaos.
There are FFA modes like mace and netherite smp and the whole vibe is train and dominate.

GG.MINEWIND.NET New Server IPHardcore Factions Returns Competitive PvP 1.21.11

I found a new competitive PvP server that is trying to reinvent Hardcore Factions. The people making it are doing it as a passion project and they used to play servers like Kohi and MineHQ.
There is Hardcore Factions style gameplay and there is also a Practice mode for fighting and an SMP mode too. They are trying to bring back that old HCF community feeling again even if it is kind of dead right now.
The server is on version 1.21.11 and they want feedback from players.
