I think that these arguments (especially the highlighted one) are more akin to denial of reality. When I do my research, I interpret numbers with great caution and an attempt to understand them, instead of trying to deny them or misunderstand them. Armenians and Georgians had the lowest winrates when they got released, but both had 2+% pickrate. These pickrates then dropped drastically. Shu have the 9th highest winrate, are a new civ, and are at a pitiful 1.67% (even though there are currently 50 civs, so with perfect distribution, all would be at 2%). Khitans carry it heavily, and the winrate definitely helps. But I really want to see the real numbers when the data get released, including Jurchen pickrate.
Check out a reply I made here, with more research and thorough numbers:
