Change for Rengar's ultimate to be more counterable!

I had a dream last night about league of legends. I was reading the patch notes for a couple of champions, mostly just weird stuff that i dont remember but i remember the last thing i read before I woke up. Rengar does all of his damage half of his damage when his ult is active over a couple seconds.

I really stand behind this idea because it allows the Rengar player to not have to change the play style (again, poor Rengar players:\ ) they are used to and allows for every champion (even Sona, Janna and Nami!) on the enemy team to at least have a chance of surviving even if the damage would have been fatal had it been taken directly instead.

Im updating this so instead of doing full damage over time Rengar does half his damage upfront and half of it as bleed. (you would be doing exactly the same damage as before, only your damage would be done over a longer period)

I want to hear your guys thoughts on this! :D
