Nerf junglers because top laners are abusing jungle items
Yep, sounds about right. I don't see why the changes are supposedly to help stop smite/tp top from being cancer, but in turn just damage junglers even more. LANES abuse a jungle item, so lanes are punished. I don't see why Riot couldn't just tack the %HP onto a different item. Cinderhulk could've been completely untouched stat and passive-ramping wise, and just had the %HP moved to a new item (or even Warmogs).
It's pretty obvious people want the %HP, and the Challenging Smite and AoE is just icing on the icing of the cake. As long as people still get %hp I don't think nerfs really matter much. The item could give literally 0 HP and no AoE, and people would buy it because you're still getting like 2k HP from the passive.
