NO, no, no, no. There's no way that clairvoyance should break stealth. This would make it really OP. To tell you honestly, many champions would really be affected greatly like Twitch, Rengar, Kha'zix, Evelynn, Akali,Teemo, etc. These champions are already balanced and then you "hard counter" them with clairvoyance? Rito said they don't want want total hard counter things in the gameplay like DotA (please don't argue with this) because they only wanted skill, plays, and teamwork from us. So to conclude, clairvoyance should not break stealth. Thanks for this suggestion but we should really maintain the balance of each summoner spell :)
