I found a competitive survival server hosted in EU London and it is all about fighting other players
The main mechanic is strength levels. When you kill a player you gain 1 strength and when you die you lose 1 strength so your power shows how well you are doing
It has fast villager trade restocking and trade cycling. There is a TPA system and it can even handle offline requests. Combat logging gets punished automatically and there is inventory rollback if it is needed. It also has proximity voice chat
The rules are strict on cheating and duping. You cannot build bases below ground. Ganking is allowed and traps are allowed. If you log out in combat it will kill you
