Idea being, in Classic Era Speedrun's Engineering Dummies are a real thing and beeing able to precisely call a dummy-stack is pretty useful.
This WeakAura also has some Custom Options. You can Sort by Class and Resource, toggle that death or disconnects can be sorted too and exclude Names and Classes.
It is build to work like this:
It assumes, everyone is Engineering and has Dummys because that's simply easier and no overhead, easy to setup aswell in Custom Options. It shows a bar for every player. Dummies also have a shared-Cooldown pool with for example Mana Agate etc and those are kept track aswell. Whenever someone uses those Items, it simplys goes on a 2 Minute Bar Duration. Whenever someone actually summons a dummy, it assumes a 5sec timer (thats the initial first threat) and after that it resumes to show the remainder cooldown. This is visible shown with a blue bar and pixel glow. If a dummy dies early, the cooldown remainder is shown early, the glow deactivated etc. Whenever someone dies, the bar goes red - it is supposed to detect resurrects** aswell as disconnects which are colored dark-grey.
Shared Cooldown IDs are initialized under Actions as aura_env.spellIDs and aura_env.dummySummons. Active Dummy-data is stored in aura_env.dummies.
