A few plugin suggestions that I've seen on previous survival servers I played on.
GriefPrevention
A plugin that allows you to create a claimed area where only the owner can build. It has buld in features like subclaims. (claims in claims for things like renting), /trust /containertrust and that kind of stuff.
By voting/buying a rank you will get more claimblocks.
Cube likes to have their own plugins, so I doubt that they will use such a common plugin. You know, originality and stuff (cue battle zone)
A warp plugin
Everyone can set warps to their base, mobfarm, biomes etc.
Higher rank's can have more warps.
maybe idk
Silkspawner.
This is a plugin that allows you to break spawners with silk touch. With this plugin you can place the spawner somewhere else to build some amazing (community) mobfarms.
A little problem with this. You can create some insane mobfarms who will cause some lagg.
I once made a mobfarm with 36 spawners, and yes, that laggs if maxentitycramming (A vannila minecraft gamerule) is disabled, just set it to around 100 and after 100 mobs on 1 blocks they will die.
Keep the MaxEntityCramming vanilla, at 24.
Also no please not the silk touch spawner stuff. It makes farming too easy creating a huge wealth gap and stuff. I'm all in for mobfarms and stuff, but I want it as vanilla as possible.

Can't have a problem with the plugin if it doesn't exist
:thinking:
ChestShop
With this plugin you can place signs above/on/next to chests to make a shop out of it. You can put items in here you want to sell and if someone clicks on the sign it wil buy the item with coins. This way people can create some amazing shop (really goodfor the community because people will all make their own shops)
People can still just sell items without the chest ofcourse.
The value of those things are hard to guess most of the time, which is why I prefer just trading with diamonds as standard currency (diamonds are pretty much the only currency that is not farmable and not too uncommon).
With shop plugins and stuff, people will just make giant afk farms and then sell all their stuff on the /shop, creating ridiculous inflation and a wealth gap. Plus, it's not vanilla. All in all I don't like shops with artificial currency.
