Icon shown for ShadowDance is 50/50 with icon for ShadowStrike.

Yes, this is intentional. It is showing you are supposed to Shadow Dance into Shadow Strike. It shows both for anything going into Stealth to give you time to react.

Ok. That's good info. It's not very clear just by looking at it. Would two icons with an arrow (glowing?) be a better way to communicate the intent?
