tl;dr: "Clairvoyance now reveals all enemy champions for 2 seconds, instead of revealing a target location for 5 seconds."

I... actually like it. It's strong, yes, but I'd say it's strength is fair compared to all the other Summoner Spells. It's also no stronger than its current version - except that the power is now primarily for keeping an eye on your target, rather than scouting. 120 second cooldown, at minimum, but perhaps add cooldown reduction onto an item (such as on the Farsight Orb).
