“From MMO history, from the beginning, [games like] Ultima Online had a similar, skill-based system, so we do believe it will make sense to our players,” he said.
“What we’re trying to provide to our players is flexibility. They don’t have to stick to one job: by providing this system they’ll be able to enjoy a variety of classes.”
Explaining exactly how the system’s going to work, the developer added:
“This time it’s not going to be just by killing monsters that you’ll gain experience points, but by using the weapon you hold in your hand, you’ll gain skills for that class. So, if you change your weapon you’ll change your class. You can change your class even between the battles; not during the battles.”
