Apparently neither have you... GW2 isn't Free To Play.

See that $59.99 price tag? Yeah, that means you have to buy it before you can create an account and play it. Ergo, GW2 is not free to play. Please don't use terminology if you don't know what it means.
Free to play generally (even though it is perhapps erroneous) refers to any MMO without a subscription. If FFXIV "went" f2p, you'd still have to buy the software so it won't technically be "free." to pick it up and play. DDO and LOTRO both "went free to play' but many people originally paid money for the software, making them technically not free to play.
