Or you're a glutton for pain? Haha. I played 11 for years as well, had full AF2 on warrior and most of it for Samurai and Dark Knight as well. But I also had 5 75s and most of the others at 60+, and this wasn't because I am also a glutton and loved grinding out the levels, it because I got bored running the same stuff every week.
And I am not saying that I didn't have any fun in 11, because I wouldn't have made it a year if that was the case. I am just saying, Yoshida realizes that increasing the rank every so often, gives players new direction, and that isn't necessarily a bad thing.
