[BUG] Nefarian Shadowbolted only one person during Phase 1 (logs linked)

Hello,

Last night our guild killed Nefarian. However, during Phase 1 when Nefarian was in Human form he constantly kept shadowbolting just 1 person in our entire raid. Nefarian cast 33 shadowbolts and 100% of them went on just 1 target, a priest in our raid. This is likely not intended.

Here is the log proof of it:

Here’s a Twitch VOD of it (it’s from my POV, but maybe it would help?):

I think it probably has to do with him having an aggro table and targeting healers. I feel like he was chain casting at me and in videos I find on youtube from 2006, it looks like he’s targeting healers.
