What would really ruin Minecraft: If Jeb and Dinnerbone took ALL of the suggestions. They have taken a few (two in a row from a youtuber named paulsoaresjr (nametag & water breathing potion)) but if they added junk like a Herobrine dragon that kills you immidiately when you spawn and dropss 1 million diamonds when killed. Or infinite height, or any mod at ALL, then Minecraft would go to the dogs...er...wolves.
Because in 1.6 they aded horses based off of a mod.
And pistons, and ender chests, and hoppers, the modding API, the mesa biome, and the ability to run texture packs larger than 16x, and probably more that I am not thinking of.. the hiring of Searge and the people who make Bukkitcraft, and on and on and on and on..
I have a few.
-Villagers make the "herr" sound constantly.
-Diamond rain. No. Just no.
-Animals turning hostile to get their "revenge".
-Meteor rain with meteors which always land and follow you and deal damage to you AND set you on fire like with lightning.
-If you go AFK even on a server your player will make an "Uhhhhhh..." sound to distract you if you're thinking.
There's a 1 in 5 chance that every minecraft night, 12345690 zombies in enchanted diamond armour with enchanted diamond swords will come.
