The Vytal Festival Arena - Biome Selection

This is something that I've only just realised and feel dumb for not picking up on it beforehand.

Basically, I've realised that in all cases so far, the Arena's biomes have been selected in order to best suit each team. This explained why the teams all seemed to have some form of unfair advantage, and balances out these advantages by giving them to both sides.

JNPR were given the storm biome, allowing Nora to use her semblance to the best of her abilities.
Meanwhile, Team BRNZ had the forest, allowing their sniper to use her weapon to great effect.

In the next fight, Team NDGO comment on the fact that the desert biome is the same as them fighting on their "home turf". With Team SSSN, it was slightly more difficult to see, but the water actually works to Neptune's advantage when it comes to his weapon (beating three members of NDGO in one go).

Finally, in the initial battle, it can be safe to assume that Team ABRN was given the fire biome to help with Reese Chloris' weapon. With Team RWBY, the ice biome allowed Weiss to do pretty much whatever she liked.

Hopefully, we'll get to see a lot more of this in the secondary rounds of the tournament. I would say the final round as well, but that's probably when Cinder's plan will begin.
