Yeah, good old Power Creep. (Power creep is a situation in which features newly added to the game are much better/more effective that their older counterparts.) It is exactly what heppened here.
In last update Devs were like:
"Hey, there is new region now and you can craft tones of bullets here. And guess what? It's also much easier than crafting arrows we introduced few years ago. Ah, and we also added NEW recolored version of wolves that are stronger and even more annoying than the old ones. Ah and we also added NEW, recolored version of flare that is much better than the old one and designed SPECIFICALLY to counter those NEW recolored wolves."
I agree with you that it doesn't make any sense whatsover that bullets are way easier to craft than arrows. An easy fix would be to just allow players to craft arrowheads in the workbench from scrap metal, or to severely nerf the ammunition crafting, to keep things balanced. But I don't think this will ever be done. TLD's devs seem to be very oblivious about how updates and new features affect the game. Despite players' complains, with each update TLD is pushed more and more towards "zombie wolf simulator". With more and more tools at our disposal, surviving the cold, thirst and hunger is not even a challenge anymore, wolves however are only getting stronger. And because those mechanics are overshadowed by the wolves so much, the game stops being climatic and starts looking like "trick the wolf AI" type of experience. So yeah, seeing that, I highly doubt, that this arrow/bullets imbalance problem is ever going to be adressed.
Errant Pilgrim update is a total mess. I don't understand how in the world "let's make a flare, but it's better and it's blue, and you need it against timberwolves, because normal flare is not enough" idea didn't get scrapped the very moment someone proposed it. You can clearly see that older patchnotes were designed carefully to not make the old gameplay elements redundant. For example: improvised axe and knife that were added with the forge, are significantly worse than man-made ones, to balance the fact that you can craft almost infinite supply of them. If they were added now, they would probably be lighter, faster and more durable than normal tools. At some point in TLD's development the approach changed from "we are slowly adding new things, while keeping the old ones useful, in order to make the experience better and more climatic" to "new features must be stronger than the old and wolves should be primary focus of the game".
Every time i had a long break from TLD i was amazed how the game has improved during that time. Until now. So I am really worried about the direction this game is heading in. Hinterlands keeps talking about " improving the experience" but lately the updates themselves seem to contraddict that and push the game more into "zombie survival" and "new features are better" territory. New wolf behavior resembles me playing "ARK survival evolved", the game in which everything tries to kill you for no reason. And that's a really bad sign.
I know I went a bit salty with this. And I realise that majority of forum users is going to disagree with me, but current state of the game is something that really bothers me. I am open to discussion tho.
