I have nothing against F2P games but the main concern is always how screwed the actual gameplay, content gating, player advancement, and any P2W aspect becomes when the company wants to make money. For current Tera players, nothing will change basically from the current status quo except it'll be free (the same thing FFXIV went through.. but backwards) but there is no knowledge of what they might take away or add in the future. KTera (and soon JTera) have become P2W hot garbage with the patch they received today so only time will tell if NA Tera follows the same footsteps. Of course there is also the issue with unsavorys that play f2p games. We know all too well the lalafell RMT armies when 1.0 was free and how they were greatly diminished when we had to start paying.

Regardless, I'm still going to play Tera cause I have a lot more fun playing that than other MMOs currently.
