I agree with you that GDKP/boosting/botting form a feedback loop and a black economy within Era servers, however once again, neither GDKP nor boosting actually generates gold. Neither of these things ruin the economy. Now I grant you, the existence of such services does generate demand for gold, so that players can purchase these services.
However, both GDKP and boosting existed on WoW long long before Classic 19, even as far back as the original vanilla wow. They existed as ways for people to make gold within the game economy and for others to utilize their gold on their mains to gear or level up characters. This was never a problem in the past because well, for a start most people didn’t have more than one character at max and ofc, Blizzard actually banned bots with frequent ban waves and server sizes were smaller. Therefore there was never an issue with either of these.
Part of why people hate GDKP and boosting these days is because as you say, it’s part of that same black economy. This economy exists in part because when bot inflation gets so bad gold is effectively worthless Vs real world currency. Why farm gold for 5 days when you cannot realistically generate ENOUGH raw gold to buy anything ? You could work 1 hour, earn 30 euro or whatever and buy 10k gold for 10 euros or whatever and it only cost you 20 minutes. You can then boost your characters, gear your characters etc etc. This is obviously enabled by the fact that Blizzard also doesnt punish RMT.
On the flip side, many boosters are from low income countries like Iran which are sanctioned to hell and back IRL so for these people, the ability to take advantage of the massive gold supply allows them to then sell that gold on directly to RMT purchasers or back to the bot farms/gold sellers for real world dollars/euros/sterling which has a much greater purchasing power than their native currency, making this effectively a job for them. Likewise, there are GDKP guilds filled with effectively no life players who are unemployed and supplement their income by again, taking advantage of the inflationary gold supply and selling their gold back to the players directly.
I don’t dispute that both of these things are bad, but both of these things are only profitable because botting is * so out of control*. We know completely stopping the bots is an impossible task, but if Blizzard was to take a more heavy handed approach to this issue they could slow down the gold inflation by an order of magnitude.
Whilst demand for gold would still be present, if the value of gold remains reasonable then less will buy it.
If you are min wage worker and you earn £10 per hour and the exchange rate is £10/15 gold, will you buy 15 gold ? No, because you can easily farm this. If it is 50gold /10 maybe it’s more appealing but again, easily farmable via normal game play and economic mechanics. If it is £10/10,000 then you will probably just buy it right ? Because the time needed to farm or earn this gold even with inflation of goods on AH is too much.
Whilst the value of gold decreases in real terms the players generation of gold is not tied to the games economic conditions, quests still pay the same, mobs still drop the same, etc. The AH can be used as a catch up mechanic but this requires you to get lucky with drops, invest in the right materials or take up gathering professions which induces supply and thus acts as downward pressure on the sale price of basic materials.
This is why RMT went out of control In ERA.
Remove this inflationary pressure caused by bots and GDKP becomes more accessible to everyone and less profitable for those who seek to exploit it for real world economic gain, same with the boosting. It is really a non issue without the wider economic issues present in the game.
To be honest, if we just ignore GDKP entirely for a moment. Has it fixed economic problems on the servers where it has been banned ? Not even remotely. Go ask someone who swipes current exchange rate for gold on one of the new servers, 1 week in. Much worse than it was on SoD, the economy will enter rapid inflation over the next few months and by the time TBC hits it will be comparable to Firemaw in late 2023.
The only way Blizzard can solve the issue without banning bots (which I believe they don’t want to do) is by introducing price controls in the form of wow token, which doesn’t really help all that much, but simply ensures that gold sellers can only operate under the value set by Blizzard on the current market rate for gold and ofc removing demand for Bots and taking some gold out the system when people buy on the other side (for gametime). Doesn’t really solve the problem though, just allows blizzard to make a bit of money and curb the bots a bit.
Alternatively they can put price controls in place by having vendors which sell common items at hard capped prices, for example if edge masters is sold by said vendor for 2k gold, then the auction house price could never rise above this because no one reasonable would ever buy it. When someone buys it from vendor it removes the gold from the economy. However again, this destroys an economic portion of the game and allows everyone to equip themselves with the best gear even easier than GDKP by simply swiping.
There is no easy solution to this, but the solution which is healthiest for the game and for the players experience is to absolutely destroy botting. If this was done, I don’t think many people are going to have a problem with GDKP if they can go into MC and buy an item they want for, 50g they farmed for instead of 5000.
