For Craftworld Eldar,
download Yriels Raiders + Doom of the Eldar at the GW site
the craftworld eldar rules from FAQ 2010/compendium. At least use FAQ2010 in addition to the rules at GW for yriel/hero clarifications.
/ regardless of rulesets:
For a 1000pts build:
1 Dragonship - weapon batteries, launch bays
3 Wraithships - pulsars - torps
as a core.
add a 4th Wraithship (wb+ lb) or 3-4 Shadowhunters.
Vampire assault boats are a good asset.
Under official rules/compendium: never ever take Ghostships
Under mms they're a viable option.
For a 1500pts build:
add a Dragonship (wb/lb) + Wraithship (pl/tt) to above.
add vampires, aspect warriors.
In the 1500pts build you can replace a Dragonship with the Flame of Asuryan (upgrade your admiral to Hero) (Void Dragon under MMS).
I love the Flame of Asuryan modelwise & gaming wise. Many time game winner (3 Barges on its tally, Imperial cruisers destroyed in one turn, etc).
Plus I tend to go overkill on it... Hero + Max re-roll..
And I use it under 1250pts as well... yeah!
It is my favourite fleet anyway.
