User blog comment:GimmeStarfoxWii/Exhaust vs CV for Supports/@comment-5961106-20130408234041

CV = Clarivoyance, right?

I dunno, personally I feel that it has too little of an impact when not used perfectly.

5 seconds of AoE reveal on a 60 second cooldown sounds fine, though. It has the problem that sometimes it is just completely worthless; whereas Exhaust can be used to wreck enemy carries or enemy assassins or the enemy chaser.

Personally I run Teleport / Flash, Exhaust / Flash, or Barrier / Flash; usually Teleport. I know that I should be grabbing Exhaust, but I never am close enough to the enemy adc to actually... use it on them.

But then again, CV can be used to help your jungler-- or top-- which allows you to support multiple teammates simultaneously, whereas Exhaust would only allow you to support when you are there...

Hm, I should go play some premades and pick it now. This seems genius, I'm always clueless on what to pick for my other summoner spell. :D
