Legible Cast Bars?

I admittedly have a problem paying attention. So I put my target's cast bar at 200% in the dead middle of my screen. It's objectively obnoxious but it works for me.

But even that extreme measure, it's still not legible. The words are the same color as the cast bar, and they overlap. Why? The new cast bar on the enmity list has the text above the rectangle. Can I have that on the normal cast bars?
