Comprehensive collection of de/buff indicators (tanks included) and cast alerts for NH.
Trial of Valor: https://wago.io/VJgV_EixG
Emerald Nightmare: https://wago.io/V1w_zZzFb

Several of these auras include sound cues (as non-annoying as possible). These can be removed or changed through the Actions tab on a per-aura basis OR as a group. Throughout Nighthold's lifespan, these auras will be updated for completion and brevity as the raid is cleared and strategies solidify.

Nighthold - Circles for Major Abilities
WEAKAURA Updated Feb 21st 2017 User Reloe Views 11,991 Comments 1 Stars 19
Version updates:
v2 - Updated some of the colors/size/transparency but mainly, way better Performance partly thanks to Joker - https://wago.io/Vk6Z-xbKG as he modified my code and from looking at it I found some things I didn't know about yet.

This weakaura adds circle in different colors to people that are afflicted by major boss abilities. Depending on the mechanic it may change its color based on your proximity to the person and also display the duration of that debuff in seconds.
Only works with friendly nameplates enabled and you should be using overlapping nameplates, otherwise it will not represent the actual position of the players, there is an explanation in the comment section for Tidy Plates-User, unfortunately I never used elvui so I don't know where the options are for it. Generally best way to use friendly nameplates is to disable the healthbars so you only see the names.
Kuinameplates is another nameplate-addon some people use for it, however any nameplate addon works or even without an addon at all.

If not playing on an english-client you have to change the load requirement to whatever "The Nighthold" is in your language.

You are free to take this weakaura and modify it to your own needs, I tried to make descriptions as clear as possible so even if you know little about LUA you might be able to change colors/size, I'll continue to update this weakaura if anything comes up for nighthold(especially adding gul'dan mythic) and for the future if blizzard doesn't decide to get rid of these displays.

also Star Augur signs are not in this just because there are too many other weakauras and they're already so spread that I think it would just be a duplicate.
