The reality is those players don't really matter, and have probably lost interest by now. The ones who do are those who play competitively and continue to support the scene. That's the reason why the game shipped without a lot of its single player content.
It'll be nice to have more single player modes, but most competitive players won't really touch them. Personally, I would rather see resoruces put towards new characters, balance, overall refinement and support towards the competitive community.
