I want to have a say and refute a few points and even expand on some arguments you're making.
Packs of all kinds will be ran at player discretion, with so much to do in the game it then the player has to consider how much time they take running packs. If you have a lot less time, you'll start running e.x. mahadevi larders to solis for example, or dewstone to solzreed. It's up to them to discern if that 3-6g difference per pack is worth the extra time. Not everyone will always run the best silver/labor packs.
I will agree that with bundles being nerfed from proccing 5 royal seeds - > 1 royal seed that it's a lot harder to run larders. With seeds being drained from the market and player inventories, people will be less apt to do them with their market value increasing. Larders are being run A LOT less causing every other pack to constantly have low trade in % on east/west, which will decrease the overall turn in value of normal, gilda, and blue salt packs. Plus with the auroria rich packs, people are trying to make a quick buck on a lucky proc by spamming larders. Both changes are causing a huge royal seed shortage on the mainland larder situation.
I run 50ish gilda packs a day personally. There are many ways to restore gilda. The advantage of using gilda to make money is not only increased profit, but the reduced cost of raw/processed materials compared to normal packs. You are not forced to run gilda packs, if you value gilda there are ways to grind and earn a lot of it daily if that's what you focus on. But I agree the auroria ones taking 5 gilda each is a bit steep when it's a lot less profit then running a 2 gilda pack on east/west.
I actually think nerfing rich packs would level the pack % situation out across the board. Sure people don't like their easy fix nerfed it but it will fix the thousands of larders sitting in the trade outlet and them being dry on mainland. I don't think east/west packs need a buff, personally. They are plenty good as it is.
I agree with this change. These are reasonable.
Fishing itself isn't bad, but has some problems. If you're solo fishing it takes twice as long to find spots, the fish could spawn 15 minutes away from the nearest turn in. If you're low prof it takes forever. To get to high prof quickly you need to afk fish to make little to no money off dawn lake light essence.
With how fishstands and sport fish work I don't think they can change the entire system for fish and have them turn into tradepacks. I think a work around would be to craft a pack with 2-3 garg trophies of a fish, ex. 2 garg marlins, that would trade in for 150g-200g or something and take 100 labor. But that's a silly idea. We don't think of silly ideas here.
