Every few months I get the itch for RO again and start scouring RMS for servers. Nothing out there can ever beat this though and it keeps me coming back faithfully. I love the rates especially. Just the right blend of xp so you don't feel like you're grinding but not so high you rocket past levels without trying. The drop rates are wonderful too being higher in comparison to the exp rates which is a rare find. Combined with wonderful people and neat extra features it's easily top of my list.
