That's because they need revenues. With the changes they made to the SF Sin build, people without Factions would flock to the store and buy them. Same thing goes with Ursan. Same with all the other solo builds out there. They need REVENUES until their next cash cow becomes live.
Sneaky way to do it, but its just business.
Wanna know why Anet won't fix Ursan or SF Sin?
