I spend about an hour to an hour and a half each day doing some dailies. I make about 100-150k. We raid twice a week, and given my gear we're gonna say it costs me 150k a week on wipes.
So let's do some math.
100,000 X 7 = 700,000 - 150,000 = 550,000
OR
150,000 X 7 = 1,050,000 - 150,000 = 900,000
So basically, if you're doing your dailies you will have at least half a mil a week. This is not counting if you do more dailies, pvp, hard modes, etc.
