As a jungler main, i don't think Jungle is healthy now. Takes no effort for champioins to actually clear. It needs to be a decision to entirely clear the jungle or 2-3 camps and gank. Right now, some junglers can do a full clear and still have 80% HP.
Playing someone like Shyvana who has weak ganks is stupid. Shyvana should be able to full clear a jungle, but she doesn't do it any better than Sejuani, only slightly faster. Yet, the Sej has insane ganks.
They need to make the jungler more risky. If you want clear Raptors, Red, Blue, then gank, sure but you should come out with 70% hp at best. You want to clear the entire jungle, sure but you should come out with 40%.... This is especially true early game
