Mojang can make some pretty dumb changes for minecraft, i think! And I'm not talking about them fixing dupe glitches and stuff because those need ti be addressed fairly quick but I'm talking about Ender chests dropping obsidian instead of the chest itself unless you use silk touch, making it so that you need leather to craft books now, animals no longer re-spawn when you kill them so you have to breed them, making emeralds 25x rarer than diamonds, nerfing mountain biomes(I'm not sure if thats fixed or not), changing the cobble texture in 1.7.3, changing the mossy cobble texture, changing the grass colour, changing the iron texture to being linned and there may be more. The main things that bother me are the animals not re-spawning when you kill them and books need leather! The books needing leather thing REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, REALLY, BUGS ME!!!!!!!!!! What bothers you and what other changes and fixes do you know of that are not mentioned above that bothers you? feel free to let me and others know! But they have made a lot of awesome additions like trading with testificates, melons, farming pumpkins and so on!
