New server ideas

yes sir

If you get a lure 3 rod, fishing is quite easy. Pull Minecraft over to one side of your screen, and Youtube on the other side, that's what I did. That way you can watch youtube and see it

Best suggestion ever (although I haven't quite worked it out 100%).
A hardcore world (not actually hardcore).
A world where people may play with full pvp, raid, grief, no claims.
And if you die you cannot join again until the next month (hence the "Hardcore" aspect).

Chain armor in the market, since its so rare.

A rising lava server would be cool, nobody did it on minecraft before, basically you use knockback shovels in an arena to get people killed in lava while it is rising one block every few seconds. the only survivor wins.

Here's another idea, Change the End World data with the overworld data or make a custom world with end stone instead of stone, here's how it looks: you could make it an icy world, it would be cool. [The end will not generate new chunks so it will just be what you rendered] It will give the end more reason to be there. It keeps the biomes and it can even rain/snow! To do this first Render a world that you want the end to be, fly around to generate some chunks, then go to the world with the end, go to the end and render the island, go to the overworld, escape the map, then go to your world name and copy the "Region" folder and replace the Region folder in the "DIM1" folder doing this will overwrite the end chunks with the overworld's making the end a much better place.

Wouldn't that kind of ruin the point of the End, though? Especially with the changes that are being made in 1.9?

I am unaware of any 1.9 changes to the end... But if you did replace the end with a custom overworld with endstone and stuff like that you could still build those pillars and have an ender dragon.
