Note: This AddOn only works on the original 2.4.3 client, it does not work on TBC Classic.
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-TBC-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 functionality of this AddOn is severely hampered in the TBC client and benefits greatly from using the BuffLib AddOn.
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 his work with the Warrior stance logic addition.
PS: If you'd like to improve the AddOn with more spells for TBC, please make a pull request or create an issue with the updated spells (according to the format in BigDebuffs.lua).
