Heroics via the dungeon finder have been a huge game changer for world of warcraft. Most people absolutely love it (myself included) and there are definitely ways to profit from using it. Here's a list of how to make some monies off the dungeon finder tool.
- Need on the frozen orb. Every single time I run a heroic at least one or two people don't do this, but the other three do. Don't miss out on a nice chunk of change!
- Skin, mine, and herb everything you see. Loot first, ask questions later. If there is a miner/skinner/herbalist than you can say "ok you get the next node" and seriously do alternate with the person, but otherwise go to town and assume you're fine.
- Loot every mob you can. As a tank (especially a dps tank) I tend to avoid looting. Don't be a nub like me, instead loot every single thing you see.
- Use your professions to convert your loot into better items. You know the drill, but many people simply dump unmodified goods on the auction house from heroics since it's not a full stack for whatever reason. There's nothing wrong with holding onto an handful of items until they are a full stack if that's your reasoning.
