Trying to be reddit and starting out with a slew of rules are both bad ideas. Loosen up and invite people to talk about things that are Not welcome on reddit, ffs.
"Mummies/Pyramids. Mummies are too similar to husks."
Just replace husks with mummies. No one is attached to husks and the change would not negatively effect anything.
And why reject pyramids? A desert temple is already a pyramid, just not epic.
Combined slabs. If you're thinking "putting two different kinds of slabs together" would be great, it is! It just isn't going to happen.
Why?!?!?!?! Mere rejection is a slap in the face of every Minecrafter who wants the feature.
"inhibit natural creativity" is an outright lie
"inhibit natural creativity" is an outright lie
My creativity is infinite by not having a way to sit down and by not having vertical slabs. There's no way in the game to do these things no matter how creative you are. A trap door is (usually) not a substitute for a vertical slab and and there's literally no way to simulate sitting down. That's Microsoft saying they don't want to, it's nothing to do with us. And that's just the top two things on their rejected page.
I like Curse of Fragility but the rest just seem overblown, obnoxious, gimmicky, obnoxious.
