Spell Batching in Classic

Spell batching has never been removed.

@Kaivax

While we never really eliminated spell batching in WoW, we did change how (and how often) we process batches of actions coming from players, so you’re less likely to notice that processing in today’s game.

Sure, but in retail it’s almost never noticeable, in vanilla it was kind of noticeable but not horribly so, in beta it’s painfully painfully there.

So something is definitely not tuned right.
