I don't do dailies. Except the JC one, which is 100g for 5 minutes "work".

My money is made through the oft-used route of buying items on the AH, disenchanting them and selling the resultant materials, and from instances.

Heroics are just for the badges for me now, so I DE absolutely everything that drops.

I don't make anywhere near as much as I would from grinding out dailies, but I bank about 5k profit per week that way, and that's after all my out-of-pocket expenses including gems, etc, for any new gear I pick up.

That's good enough for me to have a healthy bank balance.

If I get especially bored at weekends then I bang out a few regular quests. There are plenty around that I haven't done (two whole Northrend zones are still completely untouched in fact!) and that really is amazingly easy cash.

Oh, and I do a "fun run" to MC and ZG every week too. The MC materials in particular are a real cash cow.
