I can soundly say that I want a man who named his channel creeper farts to advertise our server as the audience he brings in is sure to be mature! Its not like the current community is mature what so ever.
Fuck obsidian being unbreakable, thats the most stupid thing in the world. Otherwise make the map be the world map like it was suggested numerous times on novs.
I really like the idea of capping enchantments at a certain level. It seems like people rely on enchantments way too much in pvp. Higher enchantments than the cap would also be a really neat feature. Do not enable tp, this would allow for a small 1v1 battle to turn into a 1v5 battle. There would also be glitches etc... Server events have to happen, it's really no fun. Enable tpa, but dont allow it in combat and possibly a cooldown.
Add selling crops to the admin shops but at a low price so players will grind to get more money, once they have more money they can spend it on tnt and raiding. More grinding means more hours on the server. People should want to raid other peoples huges farms to take all there crops, sell it and stop the faction they raided money source.
Update the damn server. Most faction wars players like potions, and not just the trash ones in spawn. Allow brewing but limit a few like strength2 and invis.
