You can pretend that:
actually says:
“we’re only moving spell casts to a low-priority loop”
but it doesn’t. They were specifically talking about spell casts because of the interactions they mentioned in that same post. The simple fact that vendor interactions are batched on Classic is proof enough that they extended the batching beyond spells.
The batching we have is functionally identical to what was in Vanilla. You, nor anyone else has provided any legitimate evidence to prove otherwise.
You must really want them to keep batching…
