Insane HG

This is a little idea I've been thinking about for a while which is a bit different from other servers and adds a little spice to the game while giving more options with the EULA.

Insane HG is where players are spawned in a 4k by 4k map, the map is split into 8 regions, each region is 500by500 and in each region different things can happen.

Here are some ideas I was thinking about that could be a little 'insane' good and bad.
Zombie wave: 50 zombies randomly spawned in that region.
TNT rain: 50 tnt blocks randomly explode in a region.
Famin: everyone's hunger goes to 3 and 50% of the leaves are destroyed in a region.
Poison: everyone gets poison 2 for 5 seconds in a region.
Bad blacksmith: 50 anvils fall randomly from the sky in a region.
Burn: 10% of all wood is set on fire in a region.
Medicine: Everyone gets regen 2 for 5 seconds in a region.
Supply drop: a beacon spawns with a chest in a random place in a region, the chest contains iron armour or weapons or 1-3 diamonds.
Rest: 50% of the mobs in a region are killed.
Dinner: 50 pieces of food are dropped randomly in a region.



EULA ideas:
Coins:
You can get coins by doing the following things.
Kill: 50 coins
Win: 500 coins
Lasting 5 minutes: 25 coins
Lasting 10 minutes: 50 coins
Lasting 30 minutes: 100 coins

2 hg servers would be insane and 2 would be normal. Both are soup based though.
