I noticed a number of bugs for gunslingers in 3rd job and 4th job. 1) HOMING BEACON (3rd job): At level 20, there doesn't seem to be 420% damage on the target as indicated in its skill description. I'm still doing my usual damage numbers. 2) FLAMETHROWER (3rd job): The monsters don't receive burn damage at all. ** And I'm not too sure about this but are ice and fire capsules working? I didn't see much change to my damage when I got these capsules. 4) AIR STRIKE (4th job): Skill quest is not working.... 5) HYPNOTIZE (4th Job): Skill quest is not working too....
for number 1) (unless I'm wrong), that 420% is the damage inflicted when a monster gets hit with the egg. It's not until bullseye that you get additional % damage on the target. 2) is a known bug - no burn effect yet
