1. Right now, it doesn't cost us squat to have the server running, so we haven't yet felt any need to open up a paypal or something. Now if we do set one up, we won't be able to implement any of your suggestions because of Mojang's
EULA that was highly controversial not too long ago. Right now, Mojang only allows completely cosmetic perks for donations, so if you have any ideas for that, that would be great.
The disguise plugin, however, sounds like a really good suggestion for the server, but we will probably wait for the 1.9 dust to settle first before potentially adding it.
2. I agree, the money system on Paradise was a fun mechanic, but when you wanted to just build something really big, it was a pain. We decided to go with the free item system instead, but even that did not work out too well. Almost every new user that joined the server was confused that they didn't have creative upon joining, they were mainly misled because the server title is "Orca
Creative." Now, we have moved towards giving everyone creative mode and banning certain blocks to prevent abuse. We
could enable an economy for our old-school players, but I'm not sure if they would be keen on it if others could just go into creative mode instead. Let me know what you think of that idea.
3. This is a highly requested feature. We shyed away from it up until now because we wanted people to join for the creative aspect, no just for survival. The last thing we want is a split community. However, if it's a thing a lot of users want, we will reconsider our stance on it.
6. It's been suggested before to have a big free-for-all pvp battle in fb in between updates and it's definitely something we will do if we ever have to go into vanilla (so far spigot has been great with quick updates for major releases). During the regular server time, we might just merge the survival and your pvp idea together. This does lead to some problems with naughty nuggets killing other people and stealing their stuff, so we will have to think this over quite a bit if we ever do consider to implement it.
Thanks for the suggestions!
