I saw fireflies when I ran to Gridania earlier to buy a new bow, if things didn't change between CB3 and OB, they should still drop fireshards with a chance at crystals. As for weapons/armor check the market districts and various shops. One thing I noticed was the shops seem to carry different things between the cities. Body armor in Uldah, feet in Grid, not sure what Limsa carries atm.
Guns dont kill people. Rangers and Hunters with guns kill people.
I won't be checking anyone in the BC ward that doesn't have star over their head from now on.
