Hey all,
I've run alot of quests, and i've lvl'd my chars on both sides. And this guide is pretty good for the person who has been thru the content once or twice before. I'm running thru it now with my 43 mage, and it's helping me stay unstuck.. (hit a lvl, then the grind takes forever)
Anyways, it's in an easy to read format, and I like it. Maybe you guys will too. It's Jame's Guide.
