I would LOVE our codex if we could have some of the following:
all non vehicle or monstrous models get "Battle Frenzy: If a unit comprised wholly of models with this special rule runs in the shooting phase, it may then perform a disordered charge in the assault phase."
Wyches get a revised Dodge special rule "Dodge: Models with this special rule have a 5+ invulnerable save, this save is increased to a 4+ in close combat. If the model is a Hekatrix, Syren, or Succubus, they always have a 4+ invulnerable save."
Incubus get the following "Murderous Advance: If a unit wholly comprised of models with this special rule successfully performing a sweeping advance, they may roll 2d6 for consolidation. If the unit ends its consolidation within 1" of an enemy model, they are considered to have performed a disordered charged, the enemy may then perform overwatch but no close combat will take place this turn, it instead resumes in the assault phase during the next player turn.
Mandrakes do not get "Battle Frenzy", as they are not strictly speaking dark eldar. Instead they T4 Poisoned and rending weps and do not need a pain token to use bale blast. in addition i would give them fear and fearless.
All Coven units get 6+ invulnerable save, due to the fact they are giant meat monsters, plus i like getting SOME save
all raiders get the following special rule "Planetary Raid: IF a unit disembarks in the movement phase, it may perform a disordered charge in the assault phase." AV11 in front
Ravager gets skyfire
Jet fighter gets "Dark Light cannon" 36" S8 AP4 Assault 3 twin linked instead of dark lances, gets non blast missiles
bomber gets 3 splinter cannons that can be swapped for disintegrator cannons for free, gets pie plates
a big dedicated transport, not a expensive transporting gun boat(tantillus)
sorry it it was a bit long or in the wrong place, let me know what you guys think
EDIT: this is more than likely in the wrong place now that i look at it, sorry
