My suggestion is not the idea of having new types of enchantments, but the ability to add current enchantments to other types of tools. For example; I want to add be able to add the "Fortune" enchantment to my fishing rod in order to get more fish, or to a diamond hoe (I'm aware that those are a flat-out waste of good diamonds) to get more crops if I break my crops with it during a manual harvest. A final example would be able to add "Looting" to god bows.
It asks for tweaking of a vanilla game mechanic. It would be like asking for shovels to shoot arrows.
Shovels shooting arrows is very different than a war hammer that lights stuff on fire, or a bow that gets extra drops.
They both go beyond the normal vanilla experience. It just strikes me as something that would be added by Mojang and not EMC.
One creative aspect doesn't mean we have brought creative into EMC, It's a handy perk that some like and some dislike, but no doubt it encourages people to get Diamond supporter.
By that they mean, you can't ask " install this plungin xy please!!!" but you can suggest special extras/features, like this more enchants. You need for nearly each suggestion posted in this forum a New plugin or to modify an old.
Based off of IcC's use of the word "survival" in this post, i find it highly unlikely that they would even slightly consider making a huge change to the game as the one you want. http://empireminecraft.com/threads/worlds-loneliest-server.24896/page-2#post-474631
