The F2P games with micro transactions are good for games with "progression". The classic examples are RPGs. This allows you to spend just a couple of hours a month, leave the game for extended periods and come back to the exact same point where you left. With subscription, you pay even if you do not play.
The only such game I play is City of Heros. I already shelled out a few $$ in their shop, but that is still much less than a subscription over the time I played. On the other hand, had it not been F2P I would have not played and paid at all. That game is PvE so there is no "pay to win".
In a game like AH, there is no progression, unless you consider perk hoarding "progression". Close the account, come back in two months, start a new account and are exactly in the same spot as when you left.
