Today, for a moment I confirmed that I can use GLoSC with the Destiny2.exe. While this seemed to do the trick when I utilized the Steam Controller configuration 'Gamepad with Camera Controls' - a default configuration which effectively turns the Steam Controller into an XBox one analog - I only did this for testing purposes. Friends warned me of the potential risk of a ban for using the GLoSC overlay. I'm hoping to get answers from Bungie regarding the risk before spending 70$+ on an XBox controller for casual play. I don't recommend using GLoSC to attempt to apply configurations which combine M&K and Gamepad controls. Those types of configurations didn't work with the Blizzard launcher and GLoSC overlay, I can't imagine they'd fare better now, or that they should.
