I like the way it works, obviously not the part about bots, but the thing is, what controls the price is the amount of people selling it, they will be cheap because guilds make it way easier to farm potions and also the other methods of making money like Pardoners and Squires or something end up being not so useful for bots since you can leave your char selling and play on an alt char anyway.
Is also important to think about how far can botting take you. You will probably never be able to bot in really high-level dungens, I mean 550+, where the most valuable receipts and equipments will probably be dropped. Lower level botting will make money for selling mostly “famous” mid-level receipts, so their price would be simply be defined by bots, as people leveling up would be able to get them easier than farming (probably?).
I believe the problem is, bots won’t affect much of late game, only when it comes to potion making, simply because it’s easy to make a bot farm potion items.
My opinion and the way I’ll play: I won’t make an alchemist unless I see I’m losing big money, I won’t bot so my alchemist would not be so profitable, since I’d have to farm my own stuff. If the bots problem is completely solved and prices rise again I can make an alchemist for personal usage.
Not so sure abbout the usage of other skills, gem roasting is good, awaken is now odd but can be very good with luck.
I believe alchemists will end up having to go rank 8 to take rank 3, maybe for making level 500 potions? also some more useful crafting skill? not sure if what could be though, hope it’s just not damage oriented or anything that doesn’t work together with “This char stops at rank 8, gimme profit”.
