I recommend adding:

1. golden-apple-cooldown
2. enchanted-golden-apple-cooldown
3. ender-pearl-cooldown Added
4. remove-join-message: true Doesnt make sense for PvPManager
5. remove-leave-message: true Doesnt make sense for PvPManager
6. remove-death-message: true Can be done using gamerules now
7. improve pushback a bit like premium does

Updated with points done and denied, just missing the cooldown
