Add /Fly On Op Prison for God and above. And players will not fly to another mines if there are barries. Support: 5 Neutral:3 No support:4
Mods don't even have /fly on OPPrison. It won't be added because people will fly to other mines that they haven't ranked up to yet.
If what dyna said was true and mods can't fly, why should a donor be able to..? No support, i doubt this would be fair.
NO support! People can fly to mines they aren't at yet. Plus having fly has no use its pointless. Also some people have parkor and if you complete you win a prize, people could cheat.
Neutral. On some servers, when you fly high enough, it stops you from escaping the mine, but I doubt that they'll put a barrier.
