okay before i begin with my explanation let me state that i havent looked on forums for this and apologise in advance because im working through my phone at the moment and its alot more difficult.my idea is sort of simple so here goes: a very expensive senior staff service that would extend a predefined number of blocks in radius where all they would do is find caves and dig straight up from them in a 1 block radius.my reasoning is simple: in vanilla you can headblock glitch and look for caves, mojang is aware of this and hasnt fixed it since pistons were introduced thus its pretty much accepted as a vanilla feature. aikar on the other hand in an attempt to prevent people from looking for diamonds has disabled the feature for the most part. if a senior staff did it people could dig down to a level that they wont die from the fall clear a 2 high space then fall down all the holes and fill them with dirt. it would assist in the nether as well as overworld and could be limited to a 128 diameter from the space you agree on. naturally emc'ers generally arent okay with seniorstaffs mucking around in the wild so the price tag would have to be implicitly hefty. but i think this would make grinders less laggy (i can hear aikar moaning about grinders right now) by eliminating dark spawn spots. and possibly increase server efficiency.thoughts?
