Cruor used to be a great ideas, you farm them, trade for items, sell those items, make gil. In essence you are farming gil, the same way you are farming stackable items to sell to NPC or AH. The difference is you get to amass cruor easily compared to the normal farming methods. And you can have multiple mules set this way and repeat. Just a more convenient efficient ways of making gil in vast amount. Which you would think will render gil somewhat useless other than for buying ancient currency, alexandrite, and all those magian trial weapon items. Still don't understand why this is a problem. If you want the do things faster, you are buying other people's time and effort to cut down your own. Basic economy.
