Tau are just immune to Chaos influence, any physical psyche attack will wipe them out. Imagine the Warp as a car. The Tau can't use it (i.e. drive it), but they can be killed by someone who drives over them with it. And their immunities have somethings to do with brainwashing than strong-willed.

As for the Necron, Eldar are created by the Old Ones as anti-Necron race, their warp powers scare most Necron. If not because of Slaanesh, Eldar would ruled the galaxy by now.
