Biome and mechanics changes

Alright, here we go, biomes and related stuff. I'll dive right into this one.

1. Jungles. Yikes, these things need some serious work. Most people don't touch them with anything less than an extremely fast mobility kit, for a good reason - jungles are very enclosed spaces, and if a full iron using Ninja or Grappler comes along, you need some serious backbone and a stiff upper lip to take that much damage without being able to strategically dish some back. This means what, you ask? Make jungles a friendlier and much more open space for players, they feel tight, they feel claustrophobic, and it needs to change. I'd say remove around 3/4 of the ground bushes and half of the trees in total. Of course, to balance this out a little cocoa beans will have to spawn in increased amounts on the rest of the trees, since jungles need to stay as a viable alternative to another biome, because of...
2. Swamps. They're huge, they're flat, they're easy to access, they're the best biome in the game for any non-biome-specific kit. They contain an enormous amount of soup material and have trees included in them, many of them the ideal size for getting the perfect amount of logs to get your stone sword and soups with. My suggestion therefore is to cut down the swamp's size (not the mushroom spawn rate) by around a third in total but have a minimum spawn size, since some swamps are so small that you're just wasting time and hunger even going to them.
3. Remove certain "useless" biomes or cut their size and spawn rate a fair bit - especially ice tundras, since Frosty is much more useful when you spawn in your snow patches instead of hanging around in snow biomes. Why would you hang around in a biome that has nothing to offer for you other than Speed? The size of tundras needs some addressing, savannahs need increased mob spawn rates in order to make them feel more like a huge area somewhere far away. Additionally, the dead tundra needs a bit of a size tweak downwards as well. Finally, something that a lot of old-schoolers miss is the insanely high mountain biomes - so many kits have immense versatility on these hills that I think some more craggy, sharp hillsides would be fitting.
4. Increased spawns of more interesing biomes - I'd love to see some mushroom islands, some more difficult-to-navigate swamps here and there, or even a completely new biome of some kind.

On to some more mechanics discussion, rejoice!

1. Nerf hunger - sure, it's called the Hardcore Games, originally though it was called the Hunger Games, but that doesn't mean I want to have to eat a Soup for every 5 blocks I run, yikes. I'd say reduce the amount of hunger lost by at least 35%, so that Cannibal isn't quite as busted as it is now.
2. Nerf total sword (and thereby axe) damage by half a heart per item. Currently, BrawlHG's damage with swords and the like is far too high to be fair to any new player, and with the way certain kits work (*cough cough* Urgal, Viking, Boxer, Anchor, Specialist *cough cough*) this practically-vanilla damage is completely nuts.

Thoughts?
