Question about weapon, returning player

[Driavna]

Hey, I've recently returned to the game, just finished the ARR main scenario and currently questing in Heavensward at 64.

My weapon is still Artemis Bow Atma ilvl 100, and I have no idea whether I should go back and continue something, or if something better turns up later in Heavensward, and what I need going into Stormblood.

Hope you can help

In my modest stick to your MSQ, the gear you will need to progress will be granted as quest rewards.
