Er, half the framerate. I don't think people fully understand the nature of a BLB - they're meant to be relatively basic geometric shapes to keep framerate high and the game playable. As soon as people are converting high quality models into bricks, things start to get choppy and in that case - no, more bricks is not better.
Sorry, to me it just sounds like you're jealous about losing control of the .blb distribution.
Sounds to me like you're attempting a troll.
People have been steadily releasing small BLB add-ons, I've seen them from Space Guy and Tom and a couple of other people. You just fail to understand the ramifications of high quality bricks (which I have attempted to highlight at the top of this post for you, but feel free to ignore!)
