I'm not a supporter of subscriptions either and would rather pay twice as more the full game than paying small amounts every month. Just saying that subscription would be accepted by more people than selling in-game items with actual benefits as Bruggan suggested.
I'd prefer to pay once and have the game for eternity, even if it means that there's (somewhat acceptable) pay2win stuff in the game. As long as I can jump into the game at any time, I can even tolerate 12yo mom's money clans having slight advantage.
