If you think what you have offered is a good argument, allow me to show you why it is not.
You have made a claim. But have you considered the qualifiers for this claim?
For example, is it practical for everyone in the game to buy whatever they want using tokens? The simple answer is no. The long answer is that in theory, a very limited number of players could buy whatever they want, but for the vast majority of players, what you can actually achieve with tokens is pretty limited.
In other words, your claim is true, but only in a very limited sense.
There are a number of serious issues with this claim.
Firstly you're attempting to use as grounds for your claim, the unsubstantiated assertion that "Most players would agree". According to whom exactly? Can you back that assertion up as a solid fact, or is it just something you assume? (obviously it's the latter).
Secondly, you're trying to use a semantic argument to demonstrate that WoW is pay to win by applying your own literal definition of the words. You have provided grounds and warrants for your definition, but did you consider any rebuttals? For example, did you, at any point, bother to investigate where this term "pay to win" comes from or whether it already had an established meaning? Obviously not.
Pay to Win has an established meaning and history. If you want to apply a label to something, find out what its meaning is first, instead of deciding to use your own uninformed interpretation.
Here are a few online definitions that may not be exactly dictionary definitions (there is none) but they give an idea of what the generally accepted meaning is:
"in online gaming, the practice of buying in-game items that give a player a very big advantage over others."
"Games that let you buy better gear or allow you to make better items then everyone else at a faster rate and then makes the game largely unbalanced even for people who have skill in the game without paying"
"Any game policy where specific content needed to win is locked behind pay walls. Forcing people to pay, in order to access said content."
"Pay to Win is a situation in gaming (usually MMOs or Massively Multiplayer Online games) where companies allow you to buy items or advantages with real money that cannot be obtained normally by playing the game. An exception to the rule is that if an item/advantage can be obtained in-game but the acquisition time is unreasonably long, that can also be considered Pay to Win."
Now tell me, does the WoW token meet any of those definitions? No it does not.
If you look at all those definitions, the common theme is this: In a pay to win game, you are required to pay. Conversely, if you do not pay, you are putting yourself at a significant disadvantage to those who do.
The weakness of your claim here is that you haven't considered the possible rebuttals.
Yes, there are some similarities. But I assure it is not effectively the same thing. Why? Because you're buying the gold from other players. That has an effect on the game. Allow me to illustrate the difference:
Scenario #1:
Blizzard sells the sparkle pony in the store. When a player pays money to the store, a new mount is created and added to the game. If every player of the game paid for this mount, the only thing that would change is that everyone would now be $20 poorer and have a new mount added to their collection.
Scenario #2:
Blizzard sells the Brutosaur in-game for 5M gold. If a player wants to buy this using tokens, he needs to fork out a whopping $400. This puts 20 tokens onto the AH and 20 other players in the game who have acquired 250K of gold each, need to buy those tokens. Because of the size of the market, this single event is unremarkable and barely affects the token market. Now consider what happens if every player in the game decides they want to spend money to buy tokens to buy this mount. It cannot happen. You see, for every person wanting gold, you need a supplier of that gold. The system needs to be balanced. If the demand for gold starts increasing, the token price dips and suddenly what you thought was obtainable is not.
If buying a token for money created gold in the game, then it would qualify as p2w. But because it does not, it is not. The token is simply a means of transacting between players.
