It's true for WoW, but many more modern MMORPGs have solid characters, attacks tied to animation (remember infamous Conan thing with female characters having lower DPS because of that), raycast hit mechanics, and yes, real physics.
Usually these mechanics are not as advanced and detailed as in single-player action games, but they do exist.
