I'd really love a feature called "Global UnitIds" for combat and effect related events. What it does is simple: For obvious reasons every entity in the game must have a unique identifier (in the native code), whatever it looks like. My request is to publish this identifier with EVENT_COMBAT_EVENT and EVENT_EFFECT_CHANGED so we have a persistent way of identifying NPCs over different game clients - of course under the restrictions that are currently in effect for regular unitIds. Would that be possible @ZOS_Chiphilseberg?
In World of Warcraft they look like this: 0x00000000012729FD
Here is an example:
