Meh, that would probably cause me to stop playing.
The main reason I enjoy the F2P/Cash shop model is because I don't ever feel obligated to play. When I pay a monthly fee, I feel as if I need to get in a certain amount of playing time to justify each monthly payment. But if I spend a time fee, or buy things over time through a cash shop, I can use them at my own leisure.
A weird thought, I guess. But whatever.

Whats that? You say you want me to play Smite instead?
Me and my friends tried it for a week and got bored pretty fast so we brought him to league and he was only able to play 2 games. He couldn't stand bird view. I would probably go back to smite or even try out Dota if this happened to league.
