Let's talk about hecarim.
After the 5.24 nerfs to hecarim's hp and removing half of his passive, he is not in such a good spot right now ( 44.5% winrate according to: http://champion.gg/champion/Hecarim/Jungle ). I seriously think riot should revert the nerfs or at LEAST give back the ignore movement collision to his passive as he was already in a balanced state before 5.24. He feels so much worse to play both top lane and jungle because of the lack of unit collision (think of it as if riven could no longer animation cancel her Q.)
