Adding games to the launcher doesn't influence WoW's economy. It influences the cost of the token, sure. However it doesn't affect the overall economy.
Tokens do not inject gold into the economy. The same gold always exists. If the price jumps up 50k someone is still paying that 50k that already existed and someone will receive that same 50k.
It reduces the value of gold in regard specifically to the Token because the Token itself is worth more but it doesn't change the value of say flasks or food or change the amount of gold circulating between players. There is gold inflation naturally through expansions but its not because of the Token or adding things to the launcher or Battle.net store.
While there are similarities the EVE Plex and the WoW Token function differently in a very important aspect. With EVE Plex you can invest in it, and the market supports investing from the ground up. With Plex you can buy with ISK and resell a few months later in ISK again. Their economy is built entirely different to support that kind of playstyle. It's very interesting but it just wouldn't work in WoW.
As someone that plays both EVE and WoW, they have similar player feedback towards PLEX that you see about the WoW Token. Almost the exact same, so just adopting their market wouldn't magically fix what problems you think it has. Us regulating its growth and decay allows us to keep it from fluctuating too wildly and impacting server economies. You'd be pretty upset if you bought a WoW token and in the time it took you to list it on the market its value dropped 40% because someone decided to unload and crash the value. That can happen in EVE. That's not really a negative about the game, its just designed to allow that kind of market behavior.
The problem with the token is the price is based on the gold DISTRIBUTION within the economy rather than the values of the economy.
For an arbitrary, contrived, example when the Token price goes up doesn't mean that, say, the price of Starlight Rose goes up. It's instead based on the amount of accumulated gold players have that they are willing to spend on a token.
Obviously, individual resources in the AH have their own abs and flows, but the token economy is tied solely to EXTERNAL demand (those willing to spend cash monies on gold tokens), rather than INTERNAL demand.
The rise in token prices is because more players want tokens (for external reasons) rather than spending that money "inside" of WoW. Now it's fair to say that that's not quite fair, as someone ELSE is purchasing gold for internal purposes. Since it's a wealth transfer. But that representation of the market value of a WoW token is only tangentially related to the actual values in the economy. If players did not have a large cache of gold, they wouldn't be willing to spend it on a token, "not at these prices".
Arguably WoW is "out of tokens" right now because buyers are, rightfully, "waiting" for the token gold price of a token to go UP. Why should i buy now when the price is just going to go up? It's a deflationary event right now since the "price of gold" is going DOWN (more gold/$ right now). So, wait, cause more scarcity (fewer tokens), demand remains the same or goes up, driving the gold price of the token up and, consequentially, drive the dollar price of gold down even farther. It's late game legion, who the heck needs another 200K of gold?
None of these elements are related to the internal WoW economy.
We could, for example, certainly expect to the Token price crash, and crash hard, if, for example, BfA does NOT offer gold missions, drying up a major source of revenue for many players.
Basically the WoW token is for WoW players to participate in other BNet things and offer a safe avenue for gold selling. I pretty much doubt we're going to see an influx of CoD players buying WoW, paying for a subscription, and then playing the WoW "Gold Game" in order to "save money" on CoD.
I got 10 rares in my 50 runs which means I was getting a rare every 5 runs. 50/10 = 5. The value of these rares was 53,190g!
On average I was getting 7-8 greens per run. This means I got 350-400 greens total. 7 (greens) x 50 (runs) = 350 Greens 8 (greens) x 50 (runs) = 400 Greens
I valued these greens (including disenchanting mats) at 40,000g - 50,000g. Loot Appraiser said they were worth more but I tried to account for that. And lastly I sold about 3,500g worth of Silk and Mageweave so far. With the Value of the Rares, Greens, and DE mats if (very important if) everything sells I would net 96,690g - 106,690g
53,190g (Rares) + 40,000 - 50,000g (Greens+ DE Mats) + 3,500g (Silk & Magewave Cloth) = 96,690g - 106,690g Total Value.
This means each run was valued at 1,934g - 2,134g per run!
96,690g/50 = 1,934g 106,690g/50 = 2,134g
Each run takes 4 Minutes and 30 Seconds. Multiply these numbers by 50 and that means my total farming time was 225 minutes or 3 hours and 45 minutes total.
