The removal of the 1 tick delay from copper bulbs is being felt across the redstone community. People were given a month to play with the new copper bulb and crafter and made use of their single game tick delays to compact redstone contraptions and create very creative devices. Nothing else in the game replicates this functionality with the same flexibility of the copper bulb. Other sources of single game tick delays are bulky and immovable by pistons. This makes it difficult to fit them into compact builds or be included in slimeblock contraptions.
The changes to the crafter in 23W46A which increased the delay of the block to 4 game ticks is detrimental to the functionality of the block. Just looking at the auto crafting aspect this has significantly nerfed the speed at which the crafter operates at making many builds from previous snapshots dysfunctional. The types of builds that could take advantage of the single tick crafter delay were bulky and took a lot of effort to design to crafter as fast as they did for complicated recipes. The nerf is unneeded as it would take many of these complex machines to match the speed of player crafting since hundreds of crafts can be done in just a few seconds by a player. Aside from the crafting the crafter was also useful in making counters and clocks as it did not behave the same as a dropper. The difference in delay between a crafter and a dropper opened it up for varied uses that were not possible before and expanded the gameplay opportunities for those technically inclined.
I’d hope to see the perspectives from others on this in the replies below.
