I believe that /is coop should be implemented into skyblock. Most players have islands and their friends have other islands. Like you could use /is coop if you needed someone to build a certain something for you and then /is coop again to remove their permissions the your island. Also you can help your friend with something on their island without completely leaving your island. /is coop gives temporary permission to someones island.
Omg yess bcus lots of players request help with building gens or iron farm issues, buts its harder when you can't build on their island :l
Great in theory, probably won't happen since it will likely involve a big change to the skyblock code.
This is a amazing idea people always ask me to build them iron farms yet I don't want to leave my island so I feel bad when I cant.
That is true But it would help a lot of the new people in skyblock but it would be hard to change the codes
