Batching does not behave like it did in Vanilla

Ignore Delimicus trash pally that only picks stuff as it fits his narrative.

Batching does indeed work differently on 1.13 than it did in original vanilla. Since they tried to emulate original batching but obviously could not replicate it 100% identical you end up with some abomination version of it that shows its true colours everytime you get into the fine details of the game (which usually is most noticeable in PvP).

As they explained it themselves:

@Kaivax

There was a single game loop that processed all messages sent and received every server tick. Nowadays, the game processes multiple loops for messages of differing priorities. Spell casts are high priority, and have been for a long time.

For WoW Classic, we’re moving spell casts to a low-priority loop that will cause them to be processed at the frequency that best fits how the game actually played in version 1.12.

Edit: Point being; classic is just another pserver with more acc. security and a 15 bucks a month cost to keep said security. It in no way reflects the original client in any way shape or form.
