Since everyone's talking about the mob vote (and complaining about it), I thought I'd put in my two cents. Feel free to add to the discussion :)
1. I think people's biggest issue with the mob vote is that the losers never show up again. A lot of people suggest this, but a vote with all the losers would be highly appreciated.
2. I think another big thing with the mob vote is theming. Not so much this year (all a bunch of cute animal mobs with a specific use), but in years past the lack of theme is usually what causes most devision. For instance, last time, we had the sniffer, rascal, and tuff golem. In other words: an animal, random little scrunkle, and a golem. There was also the year with the moobloom, glow squid, and...... iceologer. Like, one of those is not like the others. Why include it there? I think the mobs should be split into themes. Like, for instance, this round, it's all animals. Next round could be for golem-type mobs, then maybe a new enemy round, and perhaps a little weirdo round (stuff like the rascal). Don't make different parts of the community fight with each other! Let all the different parts have a vote where they win no matter what.
3. Don't get me wrong, I get providing mobs for new/casual players. Like, for instance, Little Timmy isn't going use a golem that much or go warden hunting. But he's definitely going to build his little houses and tame little animals! His game's going to be more casual, and that's okay. I get catering to those fans. However, I think there does need to be more mobs for more late-game, I-am-now-god-basically players. That's why the deep dark was so good: it added to the late game experience. I personally think golum-type mobs or new enemies would fit well, but I can also see the little weirdos being made for late game features.
4. I hear a lot of people talk about wanting a biome vote, but I don't think that's feasible. Like, if planned out, the community would need to understand how long it would take to make a full-blown biome and be willing to wait. Instead of that, I think stuff like new plants/food, functional items, and small structures (i.e. wells, igloos, ect.) would be an interesting vote that would take the same amount of effort as adding a new mob.
tl;dr I like the options this year, but I think Minecraft does need to improve its vote system.
