Ragnarok online

Found out a while ago that ragnarok online has set up some free to play servers, im considering giving it a shot. Ive tried the 7 day trial a some years ago, and even though it was mostly grinding i though it was quite intertaining. multiple forums say that the free to play servers are overrun by bots looking to make some easy cash. but as i see it, most free to play mmorpg's are filled with bots. the amount of people using the free to play servers, which may cause some lag, further more only the american version of the game have free to play server and i live in europe, which may increase my lag further.
