Since the release of minecraft 1.8 and the removal Metadata's several community's have been severely crippled and force to stay downgraded at 1.7.10. Building communities that utilize Metadata's can no longer update. This includes Communities such as Ravand and Aleria, not to mention all the resource packs that once used Metadatas.

"The metadata of a block is a number between 0 and 15 which is stored along with the block when the world is saved. With this metadata you can either give a block several different types (like the different colors of wool) or you can store for example the rotation of the block (like with stairs or pistons).
You should give a block sub types if you want to create some blocks which are basically the same but with some small differences (like the color of the wool)."

Us as a community have been damaged, our work crippled because of this, and if this isn't brought back we are only going to slowly wither away as a community but together we can fight to bring them back.

I know no one likes to read long stories but this is your time to stand up and keep this community alive, all you have to do is press that simply button... you may not think it helps but it keeps this community alive. Thank you.
