In the Apocalypse rulebook, it says that flyers count as skimmers moving over 12" so all hits are glancing. With the advent of 5th edition, this of course has changed so that now skimmers moving over 12" get a 4+ cover save.
The holo-fields rule states that '...any hits are discarded on a
d6 roll of 4 or more".
So how does this work?
Option 1: Use the
Apoc RAW - flyers can only recieve glancing hits but do not get a cover save. Holo-fields give you a 4+ save against all hits.
Option 2: 5th ed invalidates
Apoc - All flyers get a 4+ cover save (effectively provided by the holo-fields) so holo-fields are redundant on Eldar flyers. Penetrating hits can occur on all flyers.
Option 3: Hybrid - After rolling to hit, the Eldar player would roll to see if any hits were discarded by the holo-field. After this any remaining hits could be negated by the cover save that applies to all flyers. Penetrating hits can occur on all flyers.
Option 1 has the problem that it makes all flyers incredibly difficult to kill by removing the 'destroyed' results (although immobilised results destroy flyers anyway), Option 2 makes Eldar flyers hideously overcosted, as they are paying for wargear that doesn't work, Option 3 makes Eldar flyers tougher than Nob bikers (well, not quite...

) but seems to be the best way of mixing 5th ed and
Apoc rules.
So what do you guys think??
