It’s nice that I can use a 1.17 client but could some of the new blocks be added. Of course some would would be game breaking in this servers context but some of the new aesthetic blocks like lanterns, chains or other things that can be crafted. Also could the nether be updated?
This was announced months ago that 1.16 is being worked on, it won't be a quick fix, they need to implement it off the server and make sure there are no exploits and bugs first, as well as plugins etc
