Physical ranged dps tend to be the lowest of a group's dpsers. This is mainly due to it's overall safety with most mechanics while not having to sacrifice uptime. So against a selfish dps like a SAM, they'd have to have pretty poor gear/skill to be on par with a BRD.

As far as dps penalty vs utility goes, the spectrum within p.ranged usually goes:

MCH as the most dps/least utility (though most would argue the inc. in dps doesn't make up for its lack of util. compared to BRD or DNC)

BRD middle of the road dps/mostly passive utility

DNC least dps/best util by a mile
