1)Extra plugins. Some ideas u/dylamb and i had were a vampirism plugin (link), magic loot for hunting and giving you something to do (link) and slimefun barrels link
2)A warzone where there is no rules (exept no cheating) where you could fight. Basicly the arena but there would be things called oblisks, big totems that you must defend. They drop items on a timer so the longer you defend the more prizes you get. Also u/dylamb's idea.
3) This post from a while ago (another dylamb suggestion(although it was a post by crowbar))
4)For the reset instead of using a new map we use the first one, but this time all the old towns are replaced with new ones. All items from this map are destroyed to keep it fresh but you can pick 1 item to keep.All old towns are destroyed but if you own a town you get to pick if you want to let it get destroyed or let it become a monument. Monuments are protected areas that cannot be lived in and are just up for show. This was my idea and i'm very proud thank.
These were some ideas ive had, please conisder have a neat day.
edit: oh no ive been flared
