Wouldn't some of that have to do with the individual add-ons?
i don't get what you mean, but the point is that these changes would allow players to do more. blockland has always been about players making things. badspot shouldn't be releasing add-ons as updates, we don't need more bricks or vehicles unless they bring in new components that enhance gameplay (e.g: tank, door bricks).
I listed things that will enhance/fix existing features (packet size lag, new vehicle types, raised brickcount) and new features that will add more functionality to the game (moving parts, buildable vehicles, technic bricks). The goal of most of these suggestions isn't instant gratification, but to expand creative/gameplay possibilities both short and long term.
