Maybe one workaround to improve disguise self is to have an option within the spell’s hotbar popup options to “Remember appearance” which allows you to store up to 3 npc or pc appearances to choose from in addition to the options available. But then, if you walk into the druid camp disguised as one of their druids, there may need to be additional dialogue options in order to pull off the ruse. So maybe Larian doesn’t want to go down this road...
