The only thing that cv needs changed is that you can't see it through Fog of War if an enemy casts it.

Then we can utilize it by positioning it correctly and thus revealing important points for less vision on the primary target. And while I loved S3 with the build to get cv on a 40sec cd,it is not needed when we have trinkets for additional vision as well.

For the "Reveal all enemy champs for 2 secs" Option:

Not good, has no difficulty and thus would be nerfed to hell 2 weeks after release. People said it would turn into another Flash. It may even turn into the new cleanse,good in crutch situations but useless otherwise and crippling if you cant get it working.

For the "Charges on CV for multiple uses" Option:

May work,highly risky though,as it would punish regular use of CV and reward CV hoarding until you need to check 1/5th of the map for someone.

But if we allow the cv to be spotted by sight and not by existance,we can play and counterplay with a viable spell. Play too safe with cv and you may miss something. Too risky and they will know.
