Ive gone through 7 four or five times, but each time i start i try to do a little more training at the beggining, i was lev 23 b4 i went against the first boss... man that took, ages, but i was with a freind at the time and we just talked and played for ages. But when i get bored i set a lev to get to , about 5 levs up, then you kind of get an inccentive to go to the next place in the game, so you can get more EXP, and diff enemys. Works for me, but you cant do that when your level 99, but then again i have nowere next to go so....meh
