Funny, I was actually thinking along similar lines ... including both a Farseer as well as a unit of Rangers in my future Dark Eldar lists.
Of course, sticking him with the Dark Lances would be fun, but what makes you believe he'd be useless accompanying the Rangers ?
One Farseer with Doom (from the Codex) and Prescience (the Divination primaris power).
Sniper, Precise Shots, Rending, Pinning, re-roll to hit, re-roll to wound, a hit of 5 or 6 grants you AP1, failing that a to-wound roll of 6 would still get you AP2. Plus the wound allocation when you roll a 6 to-hit ...
Also, these guys would get +3 to their cover saves, grating them a 2+ on most occasions.
Of course, they'd cost twice as much as the Lance Born above, heh.
But for holding an objective ...
So, how's that useless ?
