Rengar's ultimate vs camouflaged champs

Riot can you make it so that his ult won't reveal camouflaged champions? This ability is screwing over Eve and Twitch players like myself and ruining the purpose of the stealth changes. I'll give you an example.

When I was playing Twitch, the enemy Viktor came across me in my jungle when I was farming raptors. I camouflaged to get away and almost did but Viktor blew ghost + flash to catch up with me. I wouldn't have died on the previous Twitch, but I knew that he sacrificed a lot to kill me and I positioned badly.

However with Rengar's new ultimate, the knife cat can stay camouflaged for a ridiculous long time and ruins my only method of escape. I get insta-critted while camouflaged and peel is so difficult with his new empowered battle roar giving him cc immunity. A fed Rengar can kill me even if I position well while in camouflage, and it ruins the purpose of camouflage.

TLDR; Rengar's ultimate giving vision of camouflaged champions is a feature that was balanced based on the old stealth mechanic. Camouflage mechanic rewards and punishes players solely on their positioning but Rengar's ultimate breaks that rule, thus giving less counterplay for Eve and Twitch.
