A few people have recently obtained the highest gil reward achievement http://www.ffxivpro.com/achievement/540

Any thoughts how to achieve this? My guess is somethign to do with leve evaluations. Try having 8 differnt tiles, and perhaps make sure that all of them have high gill rewards (e.g. 12,500 K or more) in the hopes that 8 will cumulate into a 100K + leve on evaluation?
