Project: Gorgon is a 3D fantasy MMORPG (massively-multiplayer online role-playing game) that features an immersive experience that allows the player to forge their own path through exploration and discovery. We won't be guiding you through a world on rails, and as a result there are many hidden secrets awaiting discovery. Project: Gorgon also features an ambitious skill based leveling system that bucks the current trend of pre-determined classes, thus allowing the player to combine skills in order to create a truly unique playing experience.
The Project: Gorgon development team is led by industry veteran Eric Heimburg. Eric has over a decade of experience working as a Senior and Lead Engineer, Developer, Designer and Producer on successful games such as Asheron’s Call 1 and 2, Star Trek Online and other successful Massively Multiplayer Online Games.
Everyone can switch to any role if necessary (if they worked on their toon to be able to), so I don't see that as a big problem.
Eventually you can, but many players don't have several classes, and the gear for those classes, until they've played quite a bit. Or want to be forced to level a tank/healer class just so they can get groups when those aren't available.
