I had quite good drops from Dynamis. Maybe OP just having a really bad RNG there. lol
Also, you might need to proc those NMs before killing them to raise the chances obtaining rares. ;)
BTW, instead of cramming all your relic drops onto your mog storage, use Porter Moogle to store them (which also stores alot of special/event gear/items). Each cities has one of these npcs. Just be careful not to lose your storage slips, or all your hard-earning drops will lost as well. lol
There's also tons of item management knowledge players requires to know if they want to survive the hoarding onslaught by learning from here. ;)
