Heavy Shot

I just got rank 30 Archer so i headed to Gridania to purchase Heavy shot, however i find that the name is still yellow rendering it unobtainable, so my question is how long do i have to wait for heavy shot? Also with the stamina revisions how does it stand up to light shot and what should i be using it for?

If Heavy shot had been unobtainable beforehand you need to do the class quest in order for it to become obtainable.

Ah, thank you, do you know anything about Heavy Shot's performance post 1.18?
