I understand some achievements should take a long time to get. I'm a firm believer that if there is no effort, it's not worth doing. That said.. some of these achievements, long term or not, are ridiculous. I'm mostly looking after the corpses one. I played FFXI for seven years, I farmed giants daily, killed countless goblins in parties, and all around stomped things in the ground. I never, ever, came close to the amount of gil from mob drops as that achievement requires. Not even close.
