Does the `SPELL_AURA_REMOVED` combat log event include when an aura is removed from being dispelled, broken by melee attacks, broken by spells, broken by Divine Shield, broken by PvP Trinket, broken by Stoneform, etc?
Anything. You need to examine the other arguments in order to figure out what removed it. Currently working on a WeakAura that triggers when Fear Ward is removed from one of my party members (useful in last night's full Sunken Temple run).
