You don't listen well, do you?
the bumpmap is fine - the problem is he doesn't know how to bake down the weighted vertex normals that Overwatch uses. generally this is the first problem i've seen every single OW model have is the lack of explicit normals.
the phongexponenttexture isn't even a phongexponenttexture at all - it's a metallic mask. that's one of the primary features of PBR, that's it using metallic masks. creating a phongexponentmask from PBR is a bit more of a pain in the ass and it doesn't use the metallic map.
needless to say, this port is not good.
put some materials on those for god's sake. put some effort into it.
