The official skyblock server was lots of fun, making farms and trying to compete the baltop by making the best and most efficient design was really fun.
Why not bring it back again with a couple twists like more advanced blocks for farms, some sort of competitions, and more beginer friendly
Maybe add some custom things which help the player build a farm like preset farms just like tnt wars preset cannons and stuff
Some new way to increase the speed at which crops grow, either a local boost or server wide boost.
Or custom hoppers or chunk hoppers, just things to make the game more fun
