Crystal targeting matrix: anti-flyer?

DISCLAIMER: this is probably going to get FAQ'd.

 So with the key phrase being "full ballistic skill" , following RAW we can move tanks flat out and shoot flyers as if we have skyfire.

Applications can be a fire prism's str9 shot, a falcon's pulse laser or a waveserpent's shield. Does this solve the anti-air issues of eldar? Not really, at 25 points and "one use only" it's not exactly the most reliable investment.

Thoughts? 

6th Edition Eldar: The Solitaire

Upon reading the codex, this build just leapt out to me whilst thinking of how to get the most out of the mantle of the laughing god. Naturally whatever has this wargear needs constant access to cover for that survivability of re-rolling cover saves + Stealth & shrouding, easy fix, a Jetbike!
