What steps will reproduce the problem?

On a hunter, attack with pet without starting any attacks from your character.
On previous versions, pet threat would display in the window as soon as it damaged the mob.
On the latest version, nothing appears in the threat window until your character does damage to the mob.

• So if pet has been attacking for 5 seconds with no action from the hunter, threat window is still blank. As soon as hunter damages the mob, pet threat is shown at the correct value. Information is not being missed, it is just not being displayed.

Notes:

• Threat does not start displaying if I apply a DOT like serpent sting, only displays once damage is done
• Threat will display if mob hits hunter before pet takes aggro
• Everything is working as intended after this initial lack of information.
• This is not a addon-breaking issue, but a quality of life thing - it's nice being able to see your pet's threat lead before you start attacking.

What version of ThreatClassic2 are you using? (Stating 'latest' is not useful)

v2.20
Previously was using v2.12, updated due to Blizzard releasing their threat API.

Do you have an error log of what happened?

No, since no error occurred. Should be easy to reproduce.

Any additional information? (example: WoW language if not English) (Attach screenshots here if available, do not link externally)

I imagine this is linked to the change to using Blizzard's threat API rather than the old method, so it's possible that there is no fix available.

This is unfortunately due to the API behavior. If you did not do any damage to a mob and only your pet did, you are not considered to be on the mobs threat table (even tho your pet obviously is and you would even gain aggro if it dies) and your character gets no access to the threat information. Being in combat with a mob is not enough, you must have more than 0 threat to get access (i.e. doing damage to that mob or generating aoe threat through healing, buffing, etc.)

I would consider this a bug on Blizzards end that is working like this forever :(.
