I as well as quite a few people find things to be quite honestly boring.

Specially once you reach Ult rank. You pretty much have nothing to work towards.

I am going to quote some threads that have addressed this issue and have offered very good ways to remedy the problem and actually give some spark to the server.

Daily Challenges:
Ex: "Collect 5 diamond ore" - Reward could be something similar to a "voting note" or 1-2k meebles. This has to be mined from wild. Or something like that. It could potentially be manipulated and people would place diamond ore they had and just mined it. However, if there was a certain way to say that "this hasn't been mined before, so, 1/5 completed".

With daily quests, usually there are multipliers for getting all of them throughout multiple days. Maybe after the 3rd-ish day in a row, there could be like a 1.25x-2.0x multiplier on the rewards, to encourage daily activity and enthusiasm to gain meebles.
Along with that, there should be occasional hidden quests or funny ones that are unusual, like "throw a diamond into the lava: 1000 meebles" or something. It would make MeepCraft a lot more interesting.

I actually had some things to add to this as well. Make it so that the tasks are able to tie in with our /jobs. Maybe special tasks for people who reach certain levels of jobs. i.e. make the payments tie in with the job levels. If you are given a mining task and are a miner already. Get a bonus to your reward that is based on your job level.

Or the same with a hunter. Maybe make it so there are mobs that have to be hunted down in the wild of certain types that will give a count to a task. I.e. Go into the wild and kill 5 creepers. Or go into the wild and kill 5 witches.

Even make these tasks tie into the minigames in certain ways like. "Participate in 5 games of Infected" or "Win 5 games of laserstrike" or "Infect 10 players as a Skeleton kit in /warp Infected" and "Kill 10 players as a fisherman in /warp kitpvp" Things that can tie into already existing features.

Sure this may be complicated to do. But it could revolutionize. If you guys truly care about the well being of your server you would at the very least let this thread evolve and develop for ideas and stuff.
