When you removed infinite chaos dungeon from legit players, no matter how small. Those players have to find another sources to earn gold. In this case, it will just make them realize that “why do I grind when I can just buy the gold?”
This is, my guess, is what is happening now. There are more demands for gold and you will have a portion of players choosing to swipe to make up that gold they lost whereas others turned to RMT. This is why measures to affect players in a fight against bots will never work. You will end up with either the players leaving the game altogether out of frustration or they turn to bot gold.
A lot of people who pro-claimed they understand how infinite chaos or how bots are making their gold actually have no idea about what the bots are doing. And when AGS listening to this kind of suggestion, you will have this phenomenon occurring.
Gold is the only reason bots are here, and players need gold to progress. If there was enough gold for players to self sustain themselves, they will not need RMT gold.
One of the reason it is so bad in the West is because players from the West are not used to the idea of grinding multiple alts. They just aren’t interested in doing so and they simply do not have time. And when that coupled with the limited entries per day, players will turn to RMT
I personally still think that if a player worked their ass to get to a certain point in the game - for example to participate in Argos and other legion raids, you should reward them more.
If you are not comfortable with increasing the rewards, the other method is to let them pay 50% of their current raid earning for another raid entries. Guardians can also utilize the same method. This helps a lot actually because you will have people joining different raid groups, and each time they re-do it, they are earning gold and rewards for their own progression. Since raid still requiring 8 players, it doesn’t take away anything. So it’s essentially also a reward for your time that I think both casuals and hardcore can enjoy.
What this also will do is isolating them from turning to bot gold because they can just farm to obtain those gold.
If Inflation is a concern. You can always increasing the gold cost of honing or upgrading relic gear quality. There are multiple methods to add in the game to have gold sink, we can worry about this problem at a later day.
Then next problem is you need a new method to prevent bots from gathering materials. One good idea is to randomize the spawn points of those gathering nodes. Again, it will cause inconvenience to the players, but I think it is a minimal damage.
Another idea to adjust the gatherings can also be to set a lower limit to all gather items in the market. For example: AH lowest limit for a fish is 10g/1. Players who directly trade with each other can go lower than this price point. This method effectively can isolate the flow of gold out of the bot hand and I would think it will be easier for AGS to track down who is owning 300,000 fishes.
