Yep I pretty much think the same thing. Ever since I caped all jobs at 50, and started progressing with end game. The only thing that I bought was a shield, and the base weapon to start the relic quest. That's something definatly to spend gil on. All jobs have there own starting weapon for that quest, and they cost a lot. Its a weapon + 2 meteria's. Other than that though, I don't buy anything from the market boards anymore.

Heck only thing I sell on the market boards, is the item I get sometimes from a low level roulette dungeon. For some reason the low level dungeons have armor/weapons that you can actually sell, but everything lvl 50+ you can't sell anything that drops in dungeons. Doesn't make much since to me, but oh well.
