Thanks for this, very handy as i've just started to get back into 40K and its taking a bit to find my feet ! Got to agree with you on the pistol firing rangers though, ive seen them take down a unit of Ork Buggies with their pistols (shoulda seen his face ! priceless !!!)



...). I think bike mounted is generally the way to go, or at the very least giving him wings/jump pack and a fusion gun. Not useless, but definitely not as potent as other eldar HQ choices, mainly used for his support ability.
3 foot assault moving rending Shuriken Cannon (with bonus shots to boot...) coupled with his executioner makes him an incredibly versatile HQ. He does fit in more with an infantry based force, though, which fits more awkwardly.
