I'm wondering about the possibility of non-combat roleplay powers that characters can use. Especially casters. The Druid's life- or decay-causing effects, the Invoker's earthen chair, the Spiritist's booming voice, the Ardent's dancing flames. It's not a combat effect but adds a lot. It's one of my favorite aspects of 5E's casters. Alternatively, maybe just a note that their areas of influence can be used in any minor way that seems agreeable to all of the GM? Just a thought.
