First off Mojang, please take a second to actually listen to what your user base is telling you.

1. The copper bulb game tick was changed to instant starting in the latest snapshot. This was listed as changed to be consistent/as intended. Well the users are speaking to you and telling you we don't want it this way. We liked the 1 tick delay built into copper bulb. This expanded the ability of various redstone contraptions to be created. Take a poll if you need, but the users are all telling you that we would prefer to have this reverted to previous.
2. The crafter was nerfed on speed and no one can understand why you did it. Take a look at the video posted by Purplers. You are reducing the speed of the autocrafting, but that shouldn't matter. If we are using hoppers to fill the machine prior to it crafting, then it may add unnecessary delays. This may inadvertently complicate the use of the crafter.

Again, listen to your users. We are all collectively telling you that you made a mistake. Its okay to make mistakes, but learn from them and don't just blow us off.
