The way spell batching works is how it’s lag-free.

It used to be the norm that combat flow and PvP balance were defined and tuned in a game where spell messages were resolved less frequently. 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.
