What does it matter if I did or didn't? It does not change the "problem" with the game. I have sold gear on the RMAH and I have purchased gold with the earnings. does not mean I agree with system.
The biggest problem with the game is the greed of the people trying to make a living off off the game.
So let me get this straight. You hate D3's system because of trading, but trading was ok in D2 because it was bartering or black market? Or was trading wrong in D2 as well? What exactly is wrong with D3's system? And how does someone trying to make a (laughable) living off the game affect you?
I know nothing about d2's trading I played it solo beat it played the expansion solo beat it put it away never played it again. That's something you could not and like still can not do in D3 in a timely manor because the loot is so bad.
Now with MP it may be easier but you didn't HAVE and AH in d2 and you didn't need to trade to beat d2 with any class and you would be geared enough to farm when you got to the end.
"What exactly is wrong with D3's system?"
There are so many things wrong with it i am not sure where to even begin. Not that you really care anyway.
How much of your gear came from the AH? all of it? OK then that's number one.
It's a struggle to get gear for your class just leveling from 1-60 and more so getting the right gear to beat the game.. IE finishing inferno MP 0
That struggle never stops if you decide you want to keep playing.. you can spend 1000's of hours or 1000's of dollars/billions of gold. Cause loot sucks.
The 100% RNG system of loot generation is just a bad way to distribute loot. There is so many bad choices in how things where done in this game...
"And how does someone trying to make a (laughable) living off the game affect you?"
It effects anyone that is in just to play the game.
Trying to farm money off other players, flipping auctions and keeping gear out of players hands that can use it is not part of the game, its not fun, and it sickens people trying to gear up. Its more like being scammed by a used car salesman.
It drives people out of the game because it becomes too rich for their blood and nothing ever drops.
The paragon system is the only thing that brought people back in for a while, but the way the AH prices are now, and the new changes with 1.07 The failed PVP ridiculously priced BoA equipment and increased exp.. I can see another major drop coming soon as the game becomes more and more pointless to try.
