Creating core contexts should work fine on Wine, but WoW may not be trying to create one.
I have added this to my WoW start-up script:
MESA_GL_VERSION_OVERRIDE=3.3COMPAT export MESA_GL_VERSION_OVERRIDE
And now WoW is running successfully in OpenGL mode. It appears that WoW *requires* OpenGL 3.3 over 3.0.
