Vaalingarde beat me to saying what I wanted, and more eloquently than I planned to, but:
Half-Orcs were that only because developers were afraid playable Orcs may undermine them wanting all Orcs to be irreedeemably evil and too dumb to ever work with "civilized" people to not make the players feel bad when they kill them. The moment it became clear this is a limiting and bad worldbuilding, that stole half of its text from some racist crap said about several gorups of real people by bunch of British pricks in XIX century, there was no longer reason for Half-Orcs. The niche of "physical force focused" in itself lies in the idea Orcs are too stupid to be able to focus, which does not match their new lore and weirdly suggest Half-Orcs are only intelligent and able to work in a team due to their human genetics, which is gross. Also, we alrerady have Goliaths who are doing this stick better.
