Any idea why all nameplates turn blue when I get in combat? Can't find any option to change that behaviour.

Well blue would indicate the the mob is "safe", aka attacking you if you are a tank, or not attacking you if you are a dps. Usually this is handled automatically, but wasn't working properly until the latest release.

You can force your role to tank or dps under Threat & Highlighting > Threat Mode and you can change the colors under Reaction

Before updating to the latest version I would always see the red indicator with spikes when I had aggro on a mob. Now it seems inconsistent and I don't always get the red indicator/spikes when I have aggro on mobs. Is this intended behaviour or what happened between the versions? Thanks for a good addon!

This would be due to the implementation of the new threat lib for classic. When implementing it I removed the old workaround for showing aggro as that is how it is on retail. However, turns out the threat lib isn't as accurate as it seemed during initial testing.

In the newer versions this should be working as it previously did with it showing an aggro warning if a mob is targeting you regardless of what the threat says.

Okay but is it working as intended in the latest release, or is something funky still going on?
Maybe I'm just not understanding how the difference in the nameplate color is supposed to be working.

If you take a look at these four screenshots, sometimes the nameplate bar is red when the mob is aggroed towards myself, sometimes it is red when the mob is aggroed to a person in my group, sometimes it is blue when it is aggroed to either myself or others. It feels a bit inconsistent in behavior, whereas in a previous version the nameplate was always red with spikes when a mob was aggroed towards myself, and blue when not aggroed.

Sounds good !
But is my understanding here correct?:

• If I have aggro on a mob: Red with spikes
• If I don't have aggro on a mob: Blue
• If I am about to get aggro on a mob: Orange

Yes, unless you are the tank, in which case the red and blue are reversed. And the orange means you have weak aggro on that unit.

Were you in defensive stance in any of those screenshots? Because the automatic threat mode is currently very simplistic in classic when it determines if you are a tank or does.

I would recommend swapping away from the automatic mode, and setting it to either tank or dps for a more consistent experience. If this was the issue that is.

I just checked, and I was in Battle Stance in all of the screenshots. I'll try setting the mode to Tank for me and DPS for my teammate and see if that helps! Thanks.

Hmm, that shouldn't happen then. I'll look into it and see if there's something weird going on with warriors as I've never experience this.

It seems like I was reading the documentation on getting which stance you are in wrong, so this should hopefully be fixed in the next release. Not sure if that is all that was going wrong but it should at least not think you are a tank while in Battle stance.
