Why is everyone banning Diver and Assassin jungles nowadays?

mostly fuck hecarim

Because they're the strongest options around and nobody wants to deal with them being in the game.

Idk, I always ban Blitzcrank myself. I hate being told "Well just dodge the hook" as if you can do that with 100% success rate. lol

Have you look at win rate for Kha'Zix and Rengar? They are REALLY strong right now. And so is Leblanc. There's a reason you see them in LCS so much (I don't watch it constantly, but when I do I almost always see them).

No I'm banning Jayce.

There are always champions that most people ban. Those champions will change from time to time, but it's not like it's an indicator of anything other than that's what people decide to spend bans on.

Its an early game meta and assasins have good early games now, so they are banned, same with divers. When was the last time you saw or a lateish game champ in the jungle?
