@Riot, Rengar discuss pls

So before you get all mad about yet another person complaining on the forums, there is only one thing I want to address and I'm not sure if it is a bug, intended, or needs to be fixed.

Rengar, while in stealth from ult, when leaping to a target can bola in mid-leap for massive amounts of unavoidable damage. Recap consistently shows Bola doing over 1k damage when Rengar has only 2-3 items. The other part to this is because the bola lands instantly, the target is unable to flash as they are rooted, or use any other defensive ability. In the hands a skilled player, this equals instant death for the carry without any chance for counterplay.

I recently played a game as a support where I had a pink ward for every team fight. As soon as that notification came up that Rengar was nearby with ult, I dropped it in order to attempt some chance of counterplay, but with his high speed and instant damage, even that isn't enough to allow real counterplay options.

I'd like to know what the design thoughts are on this - is this working as intended?
