Not able to use steam controller

The default Xbox controller settings are not working with steam controller. Rather then having more buttons you are limited to less then original Xbox. Making a gameplay a pain in the butt as keyboard is still required. Adding launcher to steam library does not work as you need to run a game via blizzards idiotic app or connection error will prevent you from launching the game via .exe file. Spend £50 for noting. Offline mode not possible so good luck trying to ply the campaign without internet.
