After thinking it all over with a better sense of why the datablock limit is in place and how all of this works, I have a suggestion for increasing datablock limits, what if when you lowered your server brick limit, the max datablock limit would raise? I.e if I lowered it to, say, 100,000 bricks, that would raise me 28,000 datablocks(according to my understanding; it may be less). I've never gone over 60,000/70,000 bricks anyways, and other servers could still have their 128,000 limit, and I/other developers could get a huge datablock boost.
I do not, however, have an understanding of how hard this would be to implement, so if you know anything on the subject that I should be aware of/if your badspot and say it will never happen, please alert me.
