This Weak Aura is optional and can be used with conjunction to my other WeakAuras (or you can use anyone else's WA). It supports all specs.

Why? Current implementation using a trigger state updater was how I was able to achieve the growing bars and at the time (2 years ago) it was for a simple reason but now adding new features has it's limitation, i.e. multi-rend, frenzy. This gives us more flexibility by introducing cool stuff like sonar sounds and allows users to add their own modification as needed, where as the previous implementation required some background coding knowledge to make changes.
This WeakAura will WORK out of the box! I recommend following the instructions below regarding adding my addon and Masque
Highly recommend using this WeakAura with Masque + CleanUI Thin!
Masque: https://www.curseforge.com/wow/addons/masque
CleanUI: https://www.curseforge.com/wow/addons/buttonfacade-cleanui

Note: Font used in this WeakAura is called Visitor1 (which can be found in BenikUI but you can still use the WA without it)
Alternatively, if you do not want to install Details!, ElvUI+BenikUI. You can download a small add-on pack that will contain the bar texture and font https://www.curseforge.com/wow/addons/titanias-media (Does not include Masque/CleanUI!) Download, Extract `TitaniaMedia` folder into `World of Warcraft/interface/addons/`
