1-25 Pickclaws in Highpass
[then catch up on quest]
25-40 Orc Herbs and Roots. Behind Freeport and turn them in at Agent in Lake Rathe
[you can do longer than 40 but thats a good level to stop]
40-47 Dawn Maiden near Arcadin
[Everyone usually gets about 500-700CMS doing this so they dont have to worry about it]
I dont know what other people do but I use to either EG or pull tree's 47-49, do all my quest .. then go 50-60.
Lol this the easiest way to get a lvl 60 in like 2days MAX, that is if u have a high level main to help you out.
