Generally, the amount of bricks the game has without download is fine, it's just lately that people feel the lack of bricks because of all the new brick releases. I've realised that after searching for more possible bricks to make for Blockland that most of the useful ones are already made for the game. Tophius and I are working on another brick pack, and after we release this brick pack, it'll probably be the last brick pack I'll make, maybe even Tophius' too since all the useful ones are already made. Unless Blockland will someday be able to rotate bricks vertically, I don't see much more useful bricks to make.
Also, just join the servers which have these new bricks enabled, there are plenty. After all, it's up to Badspot whether he wants to make all these new brick default, maybe he can't for copyright reasons?
I personally would like the brick selection to be filled in more. There are many gaps in the library (such as 1x14, and 2x16) that would really be nice to have as it's annoying to have a spot that big and need to split it up in some hackish way with smaller bricks.
That, and inverse corner bricks should be default.
