Because Skyblock is one of the most popular subserves on the network, I figured I should contribute to the ever growing list of suggestions, so here's my take on it. 1. Island borders: This is to have a bit of privacy, and sometimes, protection from mobs that come from nearby islands, perhaps your neighbor has a terrible island that may affect the way yours look, it may also be a way to know how big your island is and to now fall off the edge everytime you hit the invisible border. 2. Trading posts: Because having shops is a bad idea, why not add a trading post? This is so that players exchange certain blocks with NPCs positioned in their own area at spawn, because some resources are incredibly valuable, or hard to get, like stained clay, stone blocks like andesite, diorite, etc... It can also add to the creativity level of players since you'll be essentially giving them a wide selection of blocks to use however they wish. 3. Difficulty levels: Skyblock is a gamemode that some people find easy, or boring, why not adjust the difficulty? Upon creation of your new island, you'll be given the option to select a level of difficulty that suits your playstyle, if taken into consideration, I'd be happy to share more information about this idea, and more... 4. Build ranks: A new feature that allows the player to interact more with staff and actually look cool in the process, got an outstanding island? Want to share your creativity? Apply for an island assessment where staff judge your island and award you with a prefix that suits your style. 5. Blueprints: An achievement-type feature where you are awarded with blueprints for creative builds provided by staff, the more achievements you complete, the more blueprints you get for you to use however you please. 6. More achievements: Nothing else needs to be said, more achievements, more challenges, more goals, more fun ! Give something for the players to look up to, there has to be some form of competition for the subserver not to fade away.
