The reason they don't usually make lean characters like that is because it's not "realistic".
...okay, I need to explain this one.
Essentially what I mean is that "In real life, where they draw inspiration from these races", animals like bears, lions, tigers and wolves are notoriously muscular. Hell, look no further than the tiger for just how massive their freaking arm muscles are.
Which is why they mostly only ever create races like those. So when you add those images as examples of what would be decently popular, I don't doubt they'd be played. A lot of people likely would play them, 100%. After all, people play Elezen (I'm sorry).
The issue is that you shouldn't always conflate popularity with design. Because one thing is "people would play the heck out of this", but it doesn't matter if most game devs just look at a big animal that sounds cool and ferocious and just makes them super buffed as a result. Traditionally, races who are that lean and jovial looking tend to be set as mages or chivalric, not a Proud Warrior Race which is usually what you tend to see from these races. Bozja, the Charr as a whole, even the Worgen exude that sort of energy. I say "traditionally", because they really don't have to be. The issue is that most game devs are older people who are used to a more conservative outlook on what race is meant to do what role in their world. We still live in a Tolkien-inspired narrative where big guys are tough warriors and lean guys are fragile magic weavers.
Sexual dimorphism isn't that bad either. It just doesn't always have to be for the lean and mean types. That's what Viera have, and it's clearly an option. I wouldn't mind at all if female Hrothgar looked bulky and large, but that's my opinion and beauty standard. I'm sure a lot of people wouldn't accept large women without calling them "too manly". If they want to make something like the one you posted, Reivaxe, they really wouldn't do too bad going for making another race. The Lupine are available :P
Reivaxe's right when she says that the "it's unpopular" argument is total BS. Furry/Beast races are popular, and not just in GW2. Hrothgar just suffer from a whole swathe of issues, many of which repel people from even trying it. I mean, why waste a Fantasia for something inferior, right? Plus, according to the census, while Hrothgar are still low on the total, they outnumber other races.
