Yi's main role is AP, not jungle. Yi's role never has been intended to be jungler. There's a reason he doesn't have the 'jungler' tag.
You can't even open with a Vamperic Sceptre on Fiora anymore, so that is null and void, and just because Phreak plays her as a jungler, in Season 2, doesn't mean anything. This is Season 3, the jungle is rougher, and no more Vamp starts. Also that doesn't address 'Fiora can't gank to save her life'.
Wow, you found one person who plays jungle Twitch. He also plays Twitch only, and has 69 CS in 25 mins in one of his games on Jungle Twitch.
Hecarim is very blue reliant as well, so blue reliant arguments are void.
Amumu with red buff sticks just as well as Hecarim with red buff.
Let me ask you then, when did you last see Jungle Alistar? Bear in mind the nerfs in S2 were intended to kill Jungle Alistar, and the changes to make the S3 jungle harder, when the cow could hardly clear the S2 jungle, almost certainly buried him.
I'm specifically saying Rammus is better at ganking early. Also if someone invades Rammus, Rammus can live long enough with Defensive Ball Curl and taunt to allow his team to collapse.
Darius is not a weak duelist. Give me a jungler that wins a 1v1 against Darius. The only one I can think of is Lee Sin, who isn't even a certainty, and *maybe* Skarner. The debuff from Crippling Strike destroys most junglers in a duel. Then there's his passive damage, and the fact Crippling is an AA reset, and he can pull you back in... I never said his ganks are *good* but if he comes from behind he is deadly, since that means you have to go past Darius, and he can save Apprehend for after you get past him, and them he has Crippling Strike, combined with his high damage. Also if the lane has C.C his can make use of his high damage too.
If you think Skarner doesn't duel well, please, play Skarner. Crystal Slash is a stronger Rampage, with permaslow, and every AA is giving him 1 second of CDR for more shields and Q's, which he can fire off about every 1.5 seconds [3.5 - 2 for AA's] Skarner's base AD is among the highest in the entire game as well. Also Fracture heals. Skarner is one of the best duelists in the entire game, at each stage of the game. His weakness lies in being kited.
No, not every jungler in the game can invade Fiddle and kill him. They get feared, and Fiddle walks away. Unless you're Lee Sin or someone who can keep on constantly jumping on him after you get on him the first time, it's hard to actually kill Fiddle.
You clearly haven't been playing against good people. Any escape skill can be used during the animation of Hecarim's E, once the autoattack HAS ALREADY BEGUN AND CANNOT BE STOPPED and it will push them further away. An Ezreal, for example, can shift behind Hecarim once the AA animation starts, and he gets pushed further away. Someone with good timing can easily use an escape skill, or flash, to force Hecarim to push the wrong way. It is that abuseable window that makes Hecarim's pre-6 ganks trivial to avoid if you have any escape skill whatsoever.
There have been cases where I literally cannot gank with Hecarim all game because the enemy team is Renekton, Fizz, Ezreal. Renekton just uses Slice as you use E's AA and gets pushed the wrong way, Fizz either uses Q or Trollpole, and Ezreal shifts as you hit him, a-la Blitzcrank hook. If your enemy has a dash that can be used as an escape, and good timing, they can easily avoid all Hecarim ganks except ones using his Ultimate.
That is my 'difficulty' with the E. People being good enough to react to it properly. I know how to use Hecarim's E fine, however, there is a short window the enemy can use before the knockback but after the AA begins, to force the knockback to go the wrong way. Which is also why you don't see Hecarim in tourny play, the players are good enough to abuse that window consistently, so Hecarim is incapable of ganking. [On top of J4, Xin and Vi slaughtering him if they ever meet him because Hecarim is an awful duelist early.]
