BigDebuffs is an extremely lightweight addon which replaces unit frame portraits with auras, stances and interrupts whenever present.
The addon menu can be accessed by typing /bd or /bigdebuffs.
To download this addon, hit the green "Code" button and then select Download ZIP.
Once the addon is finished downloading, extract the contents to your Interface/AddOns directory and importantly rename the folder from BigDebuffs-WoTLK-master to BigDebuffs.
The backport is based on BfA BigDebuffs. However, the backport does not contain any raid frame modifications (number of debuffs shown / crowd control effects) since the new raid frames do not exist in WotLK (they were implemented in Cataclysm). The backport is essentially a much improved version of LoseControl.
The backport now supports the backported version of Masque! Note: When changing anchor from Manual -> Automatic you have to reload if you are using Masque (it will look buggy until you do)
The backport now supports fully rounded corners by implementing CircleCooldownTemplate as an internal library!
Contributions
I'd like to thank the following people for their contributions to this release:
Jordon for the base addon, as developed throughout MoP-BfA (and possibly further).
Jakeswork for minor bug fixes and the Warrior stance logic addition.
Tsoukie for structural improvements (and potentially also raid frame support, in the future).
