Buff Addon - Who cast this on me?

[keLston]

Is there a buff addon that provides this sort of information?

Occasionally in the combat log, you can tell with beneficial buffs especially when they wear off who casted a buff on you.

But there are certain buffs, especially with LFR trolls, that there seems to be no way to discern who casted something on you (like Heroism/Bloodlust).

The closest thing I know to this is DBM's spelltracker module but it goes by being in the raid and providing cooldown information and tells you when someone's Heroism ends up on cooldown.

I'd like to be able to tell if someone drive by buffs me or gives me one of the cosmetic item buffs so I can return the favor. There doesn't seem to be an addon that does this so i'm not sure if it's possible? I seem to remember it being a thing once, maybe I remember poorly.
