Ah, a lack of precision in language issue. Don't get hung up on the interchangeable use of the word shield and field. Remembering these days we have Void Shields, Power Fields, Holofields, Deflector Shields, Kustom Force Fields, Warp Displacement Fields etc etc. The books aren't consistent with the use of the words. Some descriptions have gone to the trouble of describing common interactions but it would be problematic to spell eveything out in every situation, so some common sense is required.
Quote:
Holo-fields
Some units use a protective system known as a Holo-field. This device wreaks havoc on targeting systems and makes the unit difficult to hit. The dispersion of the field and the distortion it produces are dependent on both the mass and the speed with which the unit is moving. A Holo-field grants a Fixed Save against all incoming shots according to the orders it has. This save is ineffective against template weapons, as well as psychic attacks that do not require line of sight. However, any barrage template that covers the unit will always scatter regardless of whether it is direct fire or not.
Quote from current version of the Eldar book.
Just read the description of effect and the answer should be clear. Holofields work against any shot that doesn't use a template. Warp Missiles dont use a template.
Perhaps we need to ammend the Warp Missile and detail all the situations it works and doesn't work.
Warp missiles skip in and out of warp allowing them to avoid some defensive systems. Warp missiles will bypass Void Shields, Power Fields, Deflector Shields, and Kustom Force Fields. Warp Missiles are also effective against units protected by Warp Displacement Fields as they follow the unit into the Warp. Make the attack as described (in the WM description).
If a Warp Missile is fired at a unit with a hit template that is protected by the Aura of Slaanesh it will scatter 3 times (seeing we're "fixing" stuff, clearly the Aura should affect targetting of a Warp Missile. This is one option I came up with.).
