because it can destroy the point of being stranded on a sky island because its supposed to be simple.

 

Support for the biome

 

No full support: some customisations might be useful, but some are too over-powered, like No fall damage. I suggest that you just put a torch beside a water sorce or a half slab on top of it and it will not freeze. Also, for the mobs just visit /warp mob and /warp animal.

 

If you have a biome that freezes water here is a tip:

Pile up really high above the water and place a block above where a water source block is. This will stop the water freezing and (if you pile up high enough) you can't see the blocks covering the water.

If this doesn't work there is no harm in putting a few torches, glowstone, etc around the water.

 

I think the bimoe change thing might be cool, but beyond that, no support

 

Support!

 

I support being able to change the biome.
