Good old Rengar Top lane

Lets sit in bushes and build up passive stacks and Ferver of Battle stacks, jump out on the enemy from the bushes you can't see into since ward purchases can't be made, and then kill them because a free extra 20 ad on champion basic attacks is fair.

Like I mean only tanks can beat him (since they have enough tank stats to walk into the bushes and not die) and anyone else has to get screwed over in farm and in level during the early game then be potentially tower-dove at level 6 depending on how many times he jumped at you from his bushes, it just does not seem fair to me. (been seeing this since preseason started and its just annoying to play against); Is he strong, are the masteries making him stronger, or is it the ad item changes, because I just can't tell what is causing his extra damage compared to last season.

What do you all think about it?
