Every update lately gives us something epic and takes away.
v10: Gave us good bug fixes and a cool new feature where print bricks remember the last print you were using, extremely useful.
But it killed many of the great things the Left 4 Block zombie mod had to offer.
v11: Gave us bug fixes, physics, new decals, teleporting emitter things, a cool new thing where you can spray individual parts of a player, this is fun to screw around in servers with

.
But it took away many things such as name changing things and respawn bricks and such due to abuse. (I fully blame Lord Tony to be honest because he abused everything that was taken away like hell, I don't know anyone else who abused those things so badly it had to be removed from game.) It also disabled some very helpful mods like set default minigame and disable lights.
However, the things that were taken away can be dealt with. And the game is now more fun and had many things to make building more convenient.
but in my opinion, the brick physics for things like mass explosions is not fun at all. I like physics more for little tihngs you can do, like soda machines and catapults. oh, and Somebody made an air vent and you break the grate thing and you just push it off, it was such a little detail but it was cool :3
