Permanent GP10 would be scary. While I agree that certain summoner spells need buffs, this is probably not the way to approach Clairvoyance. Clairvoyance should have a significantly shorter cooldown so that way it can be used to protect split pushers, and true sight would be problematic because it would make warding significantly less important because it could just be used to discover wards (support takes Clairvoyance, automatically wins the ward war).
