An easy fix to make Rengar in better shape in the new jungle and top lane

In season 2, riot nerfed Rengar's HP regen to 4 hp per 5 and his hp per 5 per level to 0.4 due to him having overwhelming sustain with his Empowered W that did 15% of your maximum hp back then. 3 seasons later, his sustain took many hits and is nowhere near the same value of sustain as he had back then. The issue is, he still has the same low regen stats even afther many nerfs to his empowered W. Now let's compare rengar's stats to other champions who has simular or stronger sustain: Rengar: 4.27 hp per 5 at lvl 1, 11.1 at lvl 18 Irelia: 8.59 hp per 5 at lvl 1, 19,6 at 18 Yorick: 8.175 at lvl 1, 20.1 at 18 Renekton: 7.96 at lvl 1, 20.7 at 18 Warwick: 8.39 at lvl 1, 22 at lvl 18 Nunu: 8.39 at lvl 1, 22 at lvl 18 Maokai: 8.675 at lvl 1, 23.1 at lvl 18 Source: http://leagueoflegends.wikia.com/wiki/List_of_champions%27_health_regeneration

These are just a few of the example of champions who has superior sustain in their kit and still have higher HP per 5 at lvl 1 and at lvl 18, making Rengar uncompetitive in that departement. With the new jungle being very sustain reliant, it would really help him be able to clear more then 3 camps before being forced to go back to base and make his top lane a bit more viable against his counterpartners. Suggested change: HP per 5 at lvl 1 changed to 8 and hp per 5 at lvl 18 changed to 20.
