Crafting timers should exist for all items, and be applied even if you’re only selecting to craft them one at a time. Crafting timers would exist not just as a way to make crafting more difficult, but also as a way to give players an opportunity to cancel crafting, which would be important if the ability to choose to craft batches of items were quickly, easily, and obviously available in Unturned II. The amount of time per item crafted should reflect the amount of frustration there would be in accidentally creating one that you don’t need. No one’s going to be upset about accidentally crafting one more nail than they need, but they might be more than a bit peeved by turning all of their scrap metal into 2000 nails, so the crafting time per nail should probably be less than a second, and only build up to a noticeable delay if you’re crafting many of them. A makeshift car or boat, however would waste many resources and can’t be used for many different purposes, so even a single one in the crafting queue should offer an appreciable window of time to cancel. You may wonder why I would insist that crafting timers be applied, even if they’re short enough that they might be finished before you can leave the crafting interface, and the reason is that applying crafting times inconsistently would create weird and pointless incentives to crafting items individually or in multiple small batches or a singular large batch.
