I have seen some performance issues, especially on my 100x servers, when 10 people fight with all the kits they have + zombies and items spawning at the same time, its crazy chaos but due to the crazy amount of items it gets quite laggy
also another thing for the /tpkoth command, i think its quite good because PVP’ers when they get killed once in the KOTH they complain that they have to go there from all over the map again, because their beds get constantly broken.
and in the minigame when time is of the essence, its not very good that they have to spend time travelling there
