Altho I also think they could be more specific when communicating with us, I understand it in the lines of Kraken club, joyeuse multi-hit type of attacks. So in one auto-attack you could possible do 2-3 hits, with the appropriate animation. It would not matter if the DMG number showing on screen in the sum of those hits or if you actually see each DMG number for each hit, then end result would be the same; auto-attack base delay need to be slower to allow such features and to allow expansion on the battle system, more precisely on the auto-attack part of it.
