Gotta say after the flyer nerf they seem to be less desirable but since it's tlc it has just been so useful for mid tier players, most of my high level mid sized dinos was tamed by my argent like my max level thyla, bary and even my ankies and doedics, everytime i venture out, i use my argent, yeah they are kinda slow but I'm in a single player save so it doesnt really matter, plus they can stay in the air for a very long time
