You guys should add netherite to the ore collection for longer pvp battles and becoming even stronger than before, really hope you guys will take this Suggestion from me and put it into the game, this will also improve faction raids, survival, skyblock pvp, kit pvp.
Netherite only exists in 1.16; 1.16 spigot can not currently support the number of players we do without the servers running like trash. As such, other than 1.12 for survival and creative, we won't be upgrading the server, unless spigot does something to better support the newer versions.
