Oh how short everyone's memory is. You haven't experienced an exp grind until you played RF Online. Both its level exp and skill exp were grind based and not balanced to a generation of westerners that came from WoW. To level up your skills you have to use them, which most people resorted to shoving a coin under a key in your keyboard and leaving it connected overnight casting the same skill over and over again when the timer ran out to level it up. Spending a few hours to grind a level was nothing when you could spend weeks straight grinding for the next skill level. There was a reason that no one played RF in the end and it went under. They never reached the right balance in the way exp was handed out to make the people happy. (plus everyone wanted a giant bot and the teams were never balanced).
