Tank mode on Enemy List

Hello :)
as a quality of Life improvement i would really enjoy an Button to switch my enemy list to a tank mode. This means the following:

green: i have aggro on the mob everythin is fine
orange: i still have aggro on the mob but somebody clmes close (e.g. up to 70% of my aggro level)
red: i lost aggro to someone

especially the orange marker would help me a lot to find mobs i am close to loose aggro on. A huge improvement because today i need to tab between targets to find out if a dps is sneaking to my aggro niveau, especially in 8 man or 24 man content.

I agree that we definitely need the indicator for when we're on the verge of losing aggro (but haven't yet).

I don't think a button to alternate versions would be the answer, particularly not combined with reversing the meanings of the red/green indicators. (Too likely for someone to hit it by accident, not realize they've done so, and then be getting the exact opposite message than it's supposed to relay.)

Better to keep the colors always meaning the same thing (even though that does go against the typical red=bad, green=good pattern when it comes to tanks). I think they should just add a fourth color, like maybe yellow or have both a pale orange and dark orange. Give each of the four colors a consistent meaning regardless of your job, something like:

red: you have solid aggro
orange: you have aggro, but barely
yellow: you don't have aggro, but are on the verge of it
green: you're significantly far from primary aggro

A pattern like that could give both tanks and everyone else the info they need.

I agree with the replyer that flipping the colors would be bad. But I as well would like a "second place creep" indicator, basically an indicator that someone else has gone yellow, purple or blue could work, down pointing triangle shape with it, or maybe double line (equals sign =).

Aggro is orange/red square, yellow is up pointing triangle yellow, safe is circle teal/green.

The indicator shape is important for color blind players.

Also using orange might be a bad move for the verge of losing aggro color, its readability can easily be lost between red and yellow.
