for me, I have no feelings on the change one way or the other.

Its for a class, not yet released, not yet playable, which some people had issues with due to something they have no control over. I believe it was a fair change to do and take little away from an icon since I rarely focus on those icons when playing.

Icons are blue, green or reddish, tells me what they are supposed to be doing, thats about it. in the middle of a run I am hardly going to be "OH NO!!! the filled in holes bother me since I never asked for it"

chances are, in the interests of transparency they said something, if they had SAID NOTHING... no one would have noticed or complained.
