I love 1.9, but Elytra... Elytra is AWESOME! I cant wait 'til they have people flying around on Elytras! You could have a server for Elytra only, each person gets their own spot to have fun with Elytra
I like the idea, but it sounds like a lot of servers. Fantasy RPG, adventure, survival, it's a thing too many people have. Why not try something more unique? Think of your own game type, and work with that.
