Clarity & Clairvoyance

I just wanted to discuss any ideas to make these spells actually relevant, or otherwise they shouldn't even be summoner spells, because the only time I see them is to signal to your team that you're trolling. Clairvoyance is pretty much an extra blue trinket with a lower CD. Clarity is somewhat viable in early levels if your a ranged support that's mana hungry, but quickly becomes useless as you gain levels. So I was just thinking of ways to make these viable options to choose over Ignite/Exhaust/Cleanse/Heal/Teleport (cuz let's face it, Flash OP). Maybe give an AP/AS boost or something? Or maybe drain the other person of mana? Just brainstorming a bit, because otherwise they should get the Revive treatment.
