I find text of the names of the regions to be hard to read sometimes as text is rather faint and underlying map colour can make it very hard to see. Especially on while, mountainous regions. It wasn’t problem before because there was very little reason to read these texts. However now with the new missions that send you to named regions, this became a problem.
So yes, something to make regions better defined would help. May be on maximal zoom, the text and/or borders can me made to stand out (adjust contrast of the text colour and/or it’s size with the zoom level). Something like that.
