lunar dew quest on jett

I tried to get Sharks on my Cannoneer but I never got the quest for Empress' Might.

However, I know for a fact that DBs can get Vampire since every DB I saw in PvP had it.

Honestly though, almost everything Jett has is better than Sharkwave (since you can only start Empress' Might at lvl70). The only reason it's a good skill is because the two explorer pirates in 2nd/3rd job have a lacking in damage, mobbing, mobility, range, or all of the above. (Jett excels in ALL of these)

Would Cannoneer want the shark wave thing too? And it would be weird that DBs but not Cannoneers could get the UA skill quest...
