To be honest, as a ADC main I'm happy to see this coming, I don't like having games where I feed and then my team can't win because I end up getting killed by everyone on the enemy team. Once bot lane has a smaller effect on the game, maybe I'll be happy.
Junglers like Rengar, Kha'Zix, Shaco and Warwick are my demons right now, they're literally designed to make you feel bad at the game (to me at least). Rengar can just ult into your lane and with the bonus MS you can't really escape it. Kha'Zix can use his Leap to jump out at you whenever he feels like it, and its worse when he evolves it. Shaco is just insane, he's like the Akali of the jungle, he is able to blink into stealth, put out a clone, and still burst you down like hes AP but really its just leathality. Warwick's W passive is too strong to me, along with his R he will be able to go through both rivers at mach 7 speed and ult you from the edge of the river because why not. I forgot to mention Nocturne, his ult, is broken. Free ganks whenever his ult is up basically, as long as you have some form of cc, Nocturne can easily gank you.
Guess I had a lot on my mind about junglers, if riot can nerf their clear speed, that'd be great seeing that they can get lv 6 after about 2 + 1/3 clear and a successful gank.
