For me the amount of gold was not the question, rather the speed people were running heroics. I reckon I am just too cautious. I ran Gun last night using some of the shortcuts mentioned in this thread and it still took me 30 minutes via my timer addon. Considering each boss takes me about 1 miunte or less to down, the rest of the time was spent running or postioning guys for the pulls, 5 bosses = 5 minutes.
Still I suppose 5 badges in 30 minutes is not bad :P
