Jungle success is now almost entirely dictated by lane match ups
Your performance in the jungle is now almost 100% decided by your lane match ups and how they're faring, because they consistently have a large power advantage over you, and your jungle camps are now more important (but you don't have the strength to defend them against invasion from laners).
If your lanes are behind or in bad match ups, you have to concede virtually your entire jungle, and you quickly end up too far behind to even gank, with no way of catching up.
More or less all of my jungle games with Diamond players consist of the team with the advantage constantly invading the other team's jungle, and there's very little they can do about it, because the losing jungler is almost completely irrelevant, or one team has more aggressive picks (i.e. trying to jungle with a Soraka + Ezreal bottom lane will make you bash your head against a wall).
And god forbid you pick anything but one of the six meta junglers.
Why isn't this being fixed in 9.3?
