Yes but they could easily go to a Free game that doesn't limit so much of game play. They opened the game up so players would try it out, but after what I've seen said in General chat the Free they are offering is hurting it more then you would think.
True some could just buy the smallest amount of coins but most would rather not. It's like I said they are testing the waters of F2P, they lost so many subscribers when it was subscriber only this is a attempt to save the game and get more subscribers. now I'm not saying if F2P is a last resort or a This is the end, the game is dead thing. they said it themselves F2P is a chance to bring in more players to try to grab more subscribers. Its the old game of dangle the shiny thing over their heads and see who is willing to jump the highest. Plus credit sellers already were on the servers back before F2P and left when the subscribers and profits started to leave. Now that its F2P
credit farmer/sellers will be back when they just pop 5 bucks and make that and more back in profit.
