Yeah physical ranged DPS will need a buff once other casters get theirs. Its important however too keep in mind that in SB we had the opposite issue where it was physical ranged dps that were meta and most casters weren't favored in the top 1%.

You can't make all phyisical ranged as strong as casters because they have better party wide buffs than casters (minus MCH) so if you overtune them it will be SB all over again.

MCH is the exception and honestly should be doing as much as what SMNs do once they get buffed.
