Ultra lightweight dispellable/purgeable buffs on nameplates.
This Weakaura uses no custom LUA code so it should always work and won't ever need to be updated.
The buffs appear only on classes that can remove them. Enrage and Magic buffs have different glow tints so you can differentiate them faster.
It also tracks stacks and time until the debuff expires.
Being free from custom LUA code also means that you can go to Display settings and customize it to your heart's desire.
