What's sorta bugging me on servers with a crapload of bricks is the ghosting. Not like I'm pissed at waiting for it to ghost, but just the way it ghosts. Let me try to explain this...
When you spawn, you see bricks starting to appear in the distance, and in random places. For a while, you can't see anything immediately around you, which seems to be rather counterproductive if you want to start playing before all the bricks ghost. I hope I'm making sense.
What I'm thinking is that instead of ghosting in a seemingly random order (I'm not sure if there is any pattern, but there most likely is), the bricks start ghosting in a circle around you first. I presume this is possible, but there may or may not be an efficient pattern already.
