Survival. The basics of minecraft brought into a multiplayer server. Survival is surviving in the world with no help. Our current survival has a shop. The shop ruins the idea of surviving. My idea is to make it so you can only sell things. You don't need to buy things to survive. So yea, I know I'm going to get so many no supports; but why not.
I think survival should be 100% vanilla. No money involvement, donor ranks there just because. Doing everything without help of /feed, /enchant, etc.
Leave the survival server as it is just create another for you bear grylls wannabe's, All Jokes Aside I Do Kinda agree with it.
Shop? Yeah, nah, not for survival. Money though, that can be useful between player-player, such as trading... etc, and even if you feel like extorting people, protection money XD
