It was most likely shadow patched as I said. Blizzard is quite retarded, not surpised if they did that with Psyfiend.
As I also said, if you saw in 2012-2013, Psyfiend had a delay when it was spawned. It didn't cast anything for 1-3 seconds. In s14/15 it started casting instantly. There is no changelog for that, means it also got shadow patched.
This is why it's hard to report certain stuff in the game. A LOT of shit got shadow patched. This is sad, because we have people crying about stuff, but you can't prove anything because there is literally nothing you can show. No changelog, no one talks about it, no nothing.
Rip...
