Worst Rose Bride Ever
Yeah, I hear Valkyrie was created specifically to get the bots off the premium servers.
A lot of Valk players like to try and refute this claim, but it's pretty much true. Before Valkyrie, iRO had a 15 day free trial option where you could create an account and play on it for free for a while and have the option to pay for it any time after the trial was up. Gold farmers took advantage of that and would bot up practically all the maps, making it difficult to level and get decent loot. When iRO discontinued the 15 day free trials and put up the Valkyrie server, the gold sellers' bots left the premium servers and flocked to the free one. A simple yet elegant solution to getting rid of bots on P2P servers.
