User blog comment:The Rim of the Sky/ESO removing the monthly subscription: The Good and the Bad/@comment-1600847-20150122005947

Thankfully, it's not going Pay to Win... yet. You can buy mounts, disguises and potions/soul gems, but there are no items in the upcoming cash shop that give you a significant advantage over others. ZOS has stated potions/gems from the cash shop will be weaker than player-made ones. That, and a 10% increase to XP and Gold for subscribers isn't very much.

For now, it's Buy to Play, not Pay to Win. I hope with all my heart it doesn't go there ever.
