Ding 2 x 23 lvl Sorcerer yesterday.

Had 2 bar to ding to lvl 23. Took about 20 minutes grinding. Got to 23 did 30 min of questing (about 6 quests), which got me to 20% of a lvl and ran out of quests again. Grinded about 2 hours and only got up to 65% of a lvl. During this grind fest i was thinking would solo be faster. When i was thinking that a solo person came into my grind spot and started grinding. The time it took him to kill 1 mob i was about to kill 2.5 so boxing didn't slow me down too much grinding. I also read that Asmodians have the worse questing area, and you have to grind 75% of each lvl up to lvl 35, where there are more quests. I have read a post saying to get to 49 to 50 it is like 40 days of solid grinding. I don't mind grinding, but to grind 75% of each lvl is kind of getting old. So during my grind I was thinking about quieting this game. The last 4 lvls i had to grind 75% of the lvl and each one getting longer and longer. So i am either doing something wrong or this game is all about 3 hour grinds to lvl and i am not spending 40 days to get from 49 to 50.
