Perhaps for those who just registered to the C-RPG may have one-month no experience loss respec, under the level of 20?
This would be practically the exact same thing as a STF.
I remember when there was a month long waiting period on respec for STF- you'd spec one way, and you'd wait a month before you could respec. It was changed to make it even easier to try new builds. If STF were put on the main c-rpg character page, maybe you would have noticed it sooner.
I think it works beautifully at the moment, really. The new people flood in when there's a sale and if they rage in the first ten minutes and quit because they only have a pitchfork and straw hat, they leave and they're gone for good. The ones who have interest in the game do a bit more searching around and learn about STF if they pose a question in chat or whatever. Those are the ones that stick around. It gives time for people to try out new builds, make new characters, and learn the basics.
