In ST, and second coil of Bahamut, they lift all all the limitation. You can now run as many times as you like, loot as many loots as able. And they are experiencing the new loot system in regular Duns by giving you Antique pieces (be it head,body,leg,etc...), you can then use them to trade for what you want, as the same type, from the Npc, who you will get agumentated gears from, for AF2 gears. So far I love it. I will take 1/5 chance to get what I want than 1/X where X is the total number of loots drop from a turn.
