@Goldfish as far as I know it is definitely okay to comment on older suggestions if the topic is still relevant, and I definitely like your addition. :)
To add onto what Reave said, not just the bows, but the dagger apparel is immensely unbalanced too. I read on a different forum that the recipe for the ruby dagger is a lv10 recipe. However, it requires the ruby gemstone, which can be found in the Deep Deep from mining.. which requires lv62 or 63 to access. That seems absolutely wild. Why is the crafting recipe such a low level if it will still take ages to even obtain the required items?
Another thing that has been bothering me a lot lately is how skewed leveling up is within the leveling professions. When mining, as you progress through the different areas, you are able to obtain ores that reward more xp. And you have the possibility to permanently expand your cart, allowing you to level up faster. Focus on permanently, because you keep the large cart even if you go back to the lower level areas. With farming, as you level up your stash of water and compost increases, allowing you to plant bigger seeds at the same time, you unlock extra plots, allowing you to plant more seeds at the same time, ánd your yield increases.
When it comes to fishing however, you are stuck with the same measly 2xp per caught fish and leveling up doesn't add anything. Yes, at some point you can go to a new area with new fish, and for some reason the amount of fish you can catch per trip is fixed per area (rather than actually bound to your level), meaning that if I wanted to fish for a specific fish in a lower area, I am down to getting less fish than if I were to go to a higher area. Even more so, the fish themselves are worth the same too in terms of stamina. You basically gain nothing from leveling up in fishing. This all feels so incredibly skewed. On the one hand leveling up isn't really worth the trouble because you hardly get 'more' and on the other hand if you want to level up it takes literal ages to do so.
Some of these things I already touched upon in the OP, saying that leveling up should give consistent and permanent rewards throughout the professions, such as unlocking extra slots/plots/ripples, and higher levels giving actually better items. But yeah, I felt the need to get that off my chest because I've been trying, I really have been trying but fishing is such an annoying, unworthwhile and slow profession to level up.
