do I level slow?

Until October last year, my highest lvl character was a lvl 58. I am currently a lvl 137 Bishop, though granted I lvled him mostly during the Yollande opening 2x event, which lasted a month. (I went from 1-131 in three weeks of 12-14 hours a day on 4x experience.) Forget about slow or fast leveling. Play to the point that is fun for you, and that's it. At lvl 137 I am supposedly high lvl to some, but in my Khaini guild I am one of the lowest, and most of my guildies lvl much much faster than I do. If you need a rule of thumb, I would suggest allocating a certain amount of time per day strictly to training, and sticking to it. For me, that's the 4 hours of my 2x card. Ultimately, remember that all that matters is fun, and you shouldn't play to satisfy other people's definitions of that.
