- Llamas that will be replaced by Pokemon
If the inhabitants of woodland mansions even still generate with a mod update, they'd despawn in peaceful mode anyway
Cursed enchantments won't affect that many players because there isn't too much that can kill them
There aren't even vanilla villagers to trade with in Pixelmon, so the catagropher is out of luck
Since observer blocks were nerfed in the snapshots, they don't have too much to offer
Shulker boxes (i.e. "backpacks") were added
Basically, the only important new feature added in 1.11 that can really relate to Pixelmon is shulker boxes. Pixelmon's focus is not on The End, however, meaning that getting shulker boxes is basically a huge side quest. With many more items than in Vanilla Minecraft, "backpacks" are all the more handy. (I don't know if shuklers actually generate in the current Pixelmon beta, but even so...)
My idea is to add an equivalent to shulker boxes into Pixelmon, and to have it stick around through future updates. If backpacks are the only big thing we all want to Pixelmon, it would be easier to simply add them in without updating the entire mod to a new version. And under the circumstances, such a move could be a reasonable long-term feature as well.
Please let me know what you think of this suggestion. Make sure to look through the discussion as to avoid posting anything redundant.
