Male Viera as a playable character! show your support

Also on top of the fact that the concept art itself doesn't show male viera as overly buff.

No but they're certainly muscular. Muscle mass (Roegadyn and Highlanders) vs. Muscle tone and definition (basically all other non-Lalafell guys). A good example would actually be Highlander women - they're not any bigger for maxing out the muscle slider but damn, lady, do you have a license for those guns? And male Viera in the concept art were certainly dual wielding guns and a pack of ammo in their bellies. They had much better muscle definition than, say, Elezen.
Which in the first place would fit much better with their aesthetic, and I keep thinking about how Disney drew Tarzan. He was slim but obviously packing some serious muscles, which makes sense because he'd need to be both strong and nimble to be able to live on the treetops - something muscle mass would be a hindrance to as it makes the muscles firmer and harder, difficult to operate in such environments and speeds. That's a much better look for bunny folks who spend their lives not only protecting the forest but also doing it while hidden from prying eyes.
