Option to Remove the Circle Image on Skill CD

[Niwashi]

Old cool down overlay vs new cool down overlay. Not so much has changed when you examine the two side by side.

They do act differently, though, because they reversed the transparency of the overlay. For the old one, the white parts of that overlay were the transparent part that showed that portion of the normal icon, whereas the dark parts of the overlay darkened and greyed out that portion of the icon. In the new version this is reversed, with the dark parts being transparent and showing the normal icon behind it and the white areas are the overlaid bright circle.

Ignoring the more minor change of putting it within a circle to make the edge clearer (which would probably be fine on its own), the bigger difference is in reversing which section is transparent. Now, instead of darkening part of the icon, they're brightening part of the icon. So now, instead of being brightest when it's available, it's instead brightest when it's not available. As several people have already mentioned, that's the part that makes it counter-intuitive and jarring (especially when other reasons for not being available, like level sync or skills only available under certain conditions, still follow the more standard pattern of darkening them to indicate when they're unavailable).
