according to Blizzard it was 400 all the way till cata…
Thing is I bet that’s not the whole story. Its highly suspect that the complete cycle was 400ms back in vanilla and then there is the whole thing that we know is likely true, blizzard back then did some stuff client side…
Because of that it’s very possible that with processes taking place client side that the game play was indeed better on a 400 ms loop because the client would just sync every 400 ms.
However, however if that’s the case then Blizzard cant just use a 400 ms batch “artificially” because it’s impossible to make that feel correct, and I don’t think you can doing it in a modern wow kinda way…
Tuning is needed to make the game play correctly.
