Was going to say the bolded myself, it really is the only reason I haven't given my Musica anything yet.
As for v2 Archers...
Zuiha and
Oruoretta are the only ones that come to mind (I don't know if they are v2, actually). v2 Introduced the gunner class, and since then most of the op-tier arcana from the archer class are actually gunners - Tatiana, Bobomber, Mira and Baltoro, to name a few.
This is not to say current archers are bad in v2, they got buffed when v2 hit and with the coninent of sin update they got a buff that added a distance-reliant multiplier (x1 at max range x1.2 at close range, or so), if I recall correctly. Also, Sasha has a x1.5 multiplier vs slowed enemies.
Musica's bow fits debuff teams better than herself. I'd either wait for the bow raid or give her the steel bow (free quest reward).
