It's not just you, it's the fact that GW doesn't have an AH so it is very hard to make money in comparison to other MMO's. You either have to grind, spam channels to sell or spam channels to run people through missions.

Either way it's a PITA to make money in GW.

As for the topic at hand, I find that Historians and Tinkers make a killing in LOTRO. I'm a metalsmith but I did that to make my own armour. If I wanted to go where the $$ is I'd go Historian/Tinker because everyone needs Athelas pots and hope tokens.
