Last night I talked with a few people right after this happened, and no one can give a reasonable explanation to why.
Link is to Warcraft logs for a 30 sec snippet where I casted 4 scorches 1 fireball and 1 fireblast that did normal damage but the ignite did nearly 100K damage…yes 100k, not a typo. This was 2 minutes into the fight and I hadn’t casted a single spell outside of decurse prior to that point. The below graphs show the just insane spike damage that that can not be intended from a grand total of 21k damage.

I just can fathom this being intended.
