Changes to rengar to make him more of an assasin rather a tank.

As most of you know, assasin rengar kinda sucks because you can't 1 shot people and you can't escape fights. Here are my ideas for rengar changes to make him more of the assasin he was designed to be.

Change 1: Using savagery on the same target twice within 1 second deals bonus damage equal to 20/40/60/80/100 (scaling by levels put into savagery) plus 75% of rengars bonus attack damage (the bonus ad scaling is to make sure this isn't abused on tank rengar). This change gives him the ability to 1 shot squishes. Before you start saying "too op I don't want to be 1 shot by rengar" you should remember that once rengar goes in, HE CANT GET OUT UNLIKIKE OTHER ASSASINS, so I think it's fair that his burst is at least a little bit reliable.

Change 2: Bonus armor from roar, removed. This is to make tank rengar less oppressive and to make him easier to kill in fights.

If you guys have comments about these changes, I would love to hear them. And if you down vote me please explain why.
