The packaged application icons were outdated through Mojave and Catalina. With Big Sur right around the corner, and the beta on my computer, I can say that it is time to update these icons. It seems like I may be nitpicking, but I have had the battle.net and world of warcraft launcher applications buried in a folder because they do not fit the theme of all of my other icons.
What makes this so irritating is that after changing the application icons manually, they are automatically reverted on launch. I have tried changing file/folder permissions to prevent this from happening, but the application will not launch without doing so. Please change either the default icons, or leave the icons folder out of the integrity scan!
