When RO was created, it's meant for year 2000 where grind fest is cool. Now it's 2009 going 2010, where grind fest is crap. Hence to keep the game alive, the game mechanics have to be changed. Ragnarok Online will be renewed, same game with a new concept, mechanics & gameplay. Hence the Name RO Renewal for that project.

As long as it's an official server, rest assured that it WILL be bot infested.
