I see the point of having problems earning GIL with DOL and I agree that you can't make much money anymore with crafting because of the new 2.1 options to receive philo tomes. But do not forget about the advantages of your crafters. I do not know how much GIL I have saved just by not buying armor for all my classes but crafting the gear for my classes instead. Helping out your FC mates is another valuable way to make use of your crafters. And once you reached a certain level, you should at least be able to HQ your own DOH/DOL gear which saves you a good fortune as well. So crafters may not make you rich anymore but they surely help you to save money for other things you would like to have (any maybe can't craft on your own yet like 2 star HQ recipes).
