Aatrox's secondary bar color was changed to help with clarity, except it didn't.

I can't be the only one that thinks this isn't clear at all. "But the GA effect!!" In big teamfights it's extremely hard to know for sure if you have it or not, unless you look at your actual passive cooldown on the icon. Being an Aatrox one-trick for a couple years, looking at the bar has been hardwired into my brain when I'm looking to see if I have revive or not, and I get confused when I die with a red bar sometimes because I thought I had passive. This also fucks with my aggression in some teamfights, because I would look at the red bar, not being able to tell if I have it up or not, and my brain just defaulting to "Yes" because "Red bar = Revive, White bar = No Revive" has been hardcoded into my brain.

Which is why I suggest we change the color of the bar during Hellbent with no revive to Yellow, similar to this http://i.imgur.com/H0HZ1BA.png

Edit: Hell, I'd be fine with just this http://i.imgur.com/qm8hjkU.png
