Excellent, let's hear how the market bots have blocked your access to content.
You haven't described how you had access to content blocked. You've only described how you made the choice to pursue one type of content - "gleefully tanking a market" as you put it - over doing other content.
So back over your individual points.
The incentive is that you want the tools. They're not needed to do any crafting in the game, they just ease the process a bit. You can use other tools the game makes available. I know several crafters not bothering to get the Skysteel tools.
What is a top crafter? How do we determine what a top crafter is in a digital environment where all standard crafting comes with a readily obtained mathematical solution and only the RNG of Expert throws some challenge into the mix?
Because you enjoy crafting and because there are other players who need/want what you can make.
Any player can undercut you within seconds with the simple serendipity of checking their unsold listings to see if they've been undercut just after you list your items. Compulsive sellers are going to be doing this constantly because that's how they like to play the game - always checking their listings to make sure they're the lowest. You know, just like you are about to describe doing yourself.
It's crazy how often I have to tell people this but you're your own worst enemy if you keep undercutting those who have undercut you (and who then turn around and undercut you again so you have to undercut again ad nauseum). Stop obsessing over being the lowest on the MB. List then walk away and do other things. If your item hasn't sold in whatever the standard sales period is based on sales history, then worry about whether or not you've been undercut. If the item sells 4 times a day, check 6-8 hours later or longer if you're currently outside of peak traffic periods for your world instead of 6-8 minutes later.
Oh, please. Of course it's about the gil.
If it wasn't about the gil, you'd be giving away what you've made for free to any random stranger passing by because it's really about you enjoying being one of the top crafters on your world. Right?
But you don't. You list the items on the MB and then complain about how you get undercut on the MB instead because it means you're making less gil. And when you complain about making less, even though what you make is still profit above and beyond what you need, it absolutely is greed at work.
I never said anything about bots blocking personal objectives you set for yourself. I talked about blocking access to content.
They have not blocked you from crafting items. They have not blocked you from listing those items on the marketboard. They probably haven't even blocked you from selling your items if you would just take a chill pill and stop playing the undercutting game.
It's not up to the game to make certain you achieve your personal objectives. It's up to you to do that.
Being sincere and honest here - good for you. You're right, there's no reason why rings or other gear should be going for such high prices.
Yet others would accuse both of us of being bots for being willing to accept 70k instead of selling at 300k.
Except you didn't have to. You chose to do it. You decided you want to see how low the other seller would go instead of listing your item and walking away to do other things.
Can you understand the difference?
And if you genuinely want prices to be affordable for the players who "need" the items (which they don't, they can get gear from other sources that will work just fine for the content they want to do), why didn't you price the items that low in the first place?
You still haven't offered any evidence the price cutting was automated. Are you familiar with TSM, the auction house add-on in WoW? It's not automation but it makes it very easy for the player to rapidly scan and do price adjustments. Considering the other mods that players have come up with for this game, it wouldn't surprise me if there's an equivalent here. Still technically against ToS but definitely not a bot and within that grey area SE avoids discussing.
But there's also nothing to prevent a player from doing it manually if they desire considering you admit you do it yourself as you try to tank the price to see what the other seller's floor is.
Once again, you start talking about gil despite trying to claim it's not about the gil. If it's not about the gil, you would list and walk away.
That's what I do. I list and walk away. Either my item has sold the next time I go to check my listings or it hasn't. If it hasn't I check to see if the item was sold recently, at what price, and if others are currently undercutting me then I decide if I want to match the lower price (if there is one) or pull the item and sell something else instead.
I never said bots aren't a negative to the game. I abhor cheaters who aren't willing to earn their rewards through honest effort. I did say you will find there are other players who don't necessarily cheat themselves but do enjoy the lower prices that result from bot activity and so don't see it as a negative.
How are you not making "an honest living"? The honest living in this game is to beat up primals and other villains. We're the Warrior of Light, that's what we do. We even get rewarded with gil when we do it, enough for our basic game needs like repair and teleport fees.
It's the extras we want that require the extra gil. I can't account for how you don't manage to get the extra gil. I don't have a problem getting it. If I spend gil, I usually have it all back, plus a bit more, very quickly.
What have you been unable to buy in this game because you don't enough gil to do it?
As for stable economies, bots are the least of the problems with the game's economy. Unlimited resources, constant fresh gil generation, lack of viable gil sinks to drain some of that fresh gil back out of the economy, lack of price regulations, quick ventures flooding the marketboard with previously rare items, players having differing opinions about how effort should be valued, etc. - those things are what are destablizing the game economy.
Are bots a problem? Yes. There will always be players finding ways to cheat to get what they want.
Is everyone selling items on the MB and being accused of being a bot an actual bot? No. Even if they're rampantly undercutting those who are undercutting their listings, they're still doing it through human effort. You prove it when you describe how you use the same tactics against them (at least I assume you're not botting yourself).
Is it worth getting our panties in a bunch over it? No. You can still enjoy the game even if others are cheating. Ultimately, it is our satisfaction in knowing what we did and how we accomplished it that means something, not how we compare to others.
If you've got reasonable evidence that a seller is a bot (being undercut 1 minute after you list is not evidence), by all means report them to SE with as much detail as you have. I've done it myself.
But cheaters are going to cheat and it's not worth your good mental health to let them get to you.
