I started yesterday morning with 6k on my druid. I'm not boxing Wrath yet, so just running solo. After hitting 72.2 and doing 116/130 Borean Tundra quests and about 15 Dragonblight quests and turning in 25 level 70 dailes. I logged out with 6,022g last night. This includes all my skill training at 71 and 71 (18g a spell) and training up all the new First Aid, Cooking, Jewelcrafting, and Enchanting receipes I could. All the money was from quests, trash drops, mob cash drops as I DE'd everything else. So far I've only kept 1 quest reward. Had I not DE'd everything I'm sure I'd have much more cash. YMMV
