I think my shaman is 47-49, with about 4k in the bank, still wearing mostly Totemic. Perhaps you're right, but for a new player who doesn't know where the good cash camps are while leveling, I can report from personal experience that 60k by 50 is not realistic.

Regardless, I'm playing Green these days. Made a ton more plat on my druid than I did on Blue, because I learned about Hill Giants and Crystal Caverns geonids. Still only got about 6k in bank at 49, still rocking the raw-hide cloak.
