BLOOD MOON FEEDBACK

Hello summoners ! I want your opinion about something that I found interesting... Just before I start, I want you to know that I only talk English usually, so be gentle. Well, the blood moon game mode is awesome, it makes short games, huge mechanical play and fight. The Blood Moon buff is awkward, makes us become invisible / undetectable with a huge burst for the next attack. Its really nice. BUT! Something got my attention! About re Rengar , Why Rengar should be able to see us with his ultimate when we have the blood moon buff?! We're not supposed to be INVISIBLE / UNDETECTABLE? Its annoying because well, you farm and get your 3 stacks. And suddently rengar ults, every member of his team can now see you. It should be adjusted. Thanks to let me know your feeling about that.
