What did they do, make it harder so that junglers who have strong ganks..ie Lee and Elise can't clear and gank due to low hp
That's entirely not what they did. Their stated goal with the season 3 changes was not to make the jungle much more difficult, but to make it slightly more difficult while shifting the focus away from AoE into single-target. They were coming off of season 2 where junglers who had no AoE tended to be behind unless they were someone like Lee Sin (Elise was not even a jungler at the time. She was released 4 months before and was considered underpowered until she got major bugfixes and the December change to give her 25 more movement speed. Then she was played as a top. She would later be played as a support, and she would only achieve prominence as a jungler after that. The jungle was actually changed to make it better for champion like her, not worse, because champions like Elise, Xin, and any carry jungler like Yi or Trynd were considered liabilities because they had no AoE.
Even during season 3 they didn't try to punish damage-focued ganking junglers. They added spirit stone specifically to help those champions with the goal of allowing everyone to clear easily and safely. It was never their goal in season 3 to make certain champions have a hard time clearing.
-weakened all camps do they can be cleared by anyone
Are you kidding? Season 2 was the easiest clearing that there has ever been in this game. The monsters were never easier, which is why we actually saw tanks played back then. Maokai was legitimately the one of fastest jungler in the game because he could instaclear camps.
I want to make this really clear. Every ganking jungler could clear in season 2. In fact, the main thing we saw played was ganking tanks. If you played someone who needed to farm.
-increased wiggles and ff affectiveness
Feral Flare did not exist in season 3. It was released in patch 4.5, and it has only gotten nerfs since. Wriggles was considered a troll item all throughout season 3.
" They toughened the jungle to make sure ganking junglers can't clear and gank so easily,"
Not so. They toughened the jungle so that they can make it worth enough gold and experience that control junglers and fast clearers can punish champions that go off to gank and have it mean something. They also added the new items so that they can give champions who can't farm as well (like Naut for example) the option to itemize into better clears without just having an item like Elder Lizard that gives gankers all the clear they need. That's another thing you haven't noted. The new machete gives a flat amount of dps and heal to champions as they fight the camps, so champions with lower natural dps and higher resistances stand to benefit much more from it (read: tanks).
I don't think you know the history of the jungle, why certain junglers are currently good and why they weren't in the past, or how to fix it.
