A warning text that shows if your pets are not up. What seperates this from other weakaura's that do this, is that this weakaura has a slight delay in showing the text. The problem with tracking pets is that pets aren't spawned in right after loading in or dismounting, so this WA waits a couple of seconds before showing.
This weakaura is currently set to appear for Unholy DKs only. What's different from the Warlock and Hunter version is that Raise Ghoul has quite the cooldown, so the weakaura does not pop up if the skill is on cooldown.
Thanks to asakawa from the Weakauras Discord for showing me how to create the delay function in custom code
