So if I understand it correctly, WoW works fine for you with d3d9 and no overrides? If that's the case there is nothing to fix here.
Not setting MESA_GL_VERSION_OVERRIDE sounds like just another workaround to me :-|. Because as I've already said, it also works with MESA_GL_VERSION_OVERRIDE=4.0COMPAT.
