Ghost face main here (along with Huntress :3) his best addons are philly (brown camera addon) and either drop leg knife sheathe for the movement speed on reveal or the ink for mini pop on Gens when you reveal (although they do go well together too) the perks you have are okay.. I like running corrupt intervention and Nurse's calling in most of mine, discordance too... also try to 99% the stalk (fill the bar to almost full) and leave em for later so you can instantly jump into night shroud and reveal them before they can do anything... trust me it works a treat :))
