Mojang and their obsession with social media engagement sucks ass. All three of the new mobs are vaguely useful and very cute additions to the game. There's no reason we can't have all three. But they insist on this stupid system so they can have their engagement. I fucking HATE it.
Anyway here's a mod that adds all the mobs that lose the votes to the game: https://modrinth.com/mod/friends-and-foes
I've always had a little resent that they dangle mobs in front of us just to drop 2/3 of them (especially Moobloom, but they also keep teasing us about that one). But the fact that all three choices this year are so good makes me more outwardly angry that they aren't just doing all three. They have a year between updates, they can make three relatively simple mobs. Especially considering all three will probably be fully implemented by modders before the vote even happens.
I wish they would have stuck with the model of the old biome votes: all three will be added eventually, we're just picking what order they get added in. And of course the biome votes were also better because it was an updated biome and a new mob, now it's just a new mob.
