At present, if you’re not spending all of your hero points, such as you’re level 20, and saving to unlock a specialization at L21, then you’re constantly getting the red ! on the menu bar and hero build.
Please give me a way to dismiss the notification, much like you used to be able to dismiss extra trait points by going into the dialog, and exiting. With trait points, it’d come back when you got more points. With hero points, it comes back on every map load, and after every cutscene.
