Describe the bug
I don't know if it has to be fixed, or if documentation has to be updated but the event SPELL_COOLDOWN_STARTED is no longer triggered.

SPELL_CHARGES_CHANGED is triggered when a cooldown start or end, as intended
SPELL_COOLDOWN_READY is triggered as intended

For context, i wanted to make a simple TSU that check if purify/purge/.. is on cooldown or not after casting it, without using a separate cooldown trigger

That's not really documentation, so much as it is "stuff we found when we didn't have much of an idea of what we were doing". At least, that's how I treated that page at first.

But I've updated the wiki page to reflect the current state of WeakAuras.

To be clear, for anyone else who reads this, that wiki page is full of what amount to insane hacks to get things done. In addition to updating the snippet that @mrbuds mentioned, I've also removed the most dangerous ones (such as a snippet that I made years ago which would edit database data), and ones which are no longer relevant or which don't work anymore.
