I just watched the new episode and OMG I am so annoyed and borderline mad that the Aether is in the AvM universe now.
Yes, I am aware that other aspects of the AvM universe are not part of vanilla Minecraft (e.g. Titan Ravager, Note Block Universe), but all those are from the AB team's own imagination. An imagination so potent it was able to predict the Happy Ghast even before it launched. The Aether is from a mod that someone else had made a long time ago, albeit a famous one.
Okay, Monster School was from someone else, too, but it was from an animated series, not a mod. There are going to be some people who ask me what the difference is between animated series and mods, since both of them are creations from people who are fans of Minecraft. Well, here's the thing. Mods alter the game in some way, animations do not. Animations remain pure and of themselves, while mods do not.
Maybe it's because I have little knowledge and understanding of the Aether mod, but this brings me to my second argument: many people like me are not familiar with this mod. Monster School doesn't require this; you can watch it like you're watching MS itself for the first time. Watching AvM taking place in the Aether, however, requires some understanding of the Aether and its new features.
For these reasons, I am very annoyed with the Aether being in AvM.
Change. My. Mind.
