Manage your rage better with a Battle Shout tracker that starts fading-in 20s BEFORE the current buff expires. This allows you to plan ahead and avoids situations like emptying your rage on an execute kill right before the buff expires.
When the current buff has 20 seconds or less time remaining, this tracker will start to fade-in. During those 20s, the icon gradually becomes less transparent, reminding the player to save rage to rebuff soon. When the buff is gone, the Battle Shout Icon will be completely visible and Glow.
This helped me get my Battle Shout uptime from 78% to 95+% (in raids, while in battle). Maybe it helps others!
