Rumble - Was added to magic damage dealers list for completions sake. He is not as impressive as he was in the Season 2 jungle but he's fairly competent. Rather average for a magic jungler but his ganking can be obscene with his ultimate.
Malphite - Was added to the support tier because of his ability to "remove" some gold from the enemy team with his debuffs
Lissandra - Was added to the magic damage dealers. She has very powerful ganking powers but suffers severely from health sustain issues and is a terrible jungle duelist. Her ganking at Level 6 becomes insanely powerful if she can get to that point.
Yorick - Placed higher on both the bruiser (though not by much) and in the support tiers. His supportive qualities are sight (via ghouls) and the variable values of his ultimate. I felt the variable values of his ultimate are better than the artificial gold given by the other supports below him though this is also taking into account that Yorick is much stronger in jungling overall than all of them.
Trundle - Went up in the support list for the same reasons as Yorick.
Skarner - Placed higher in the tank tier (though still in tier 3) for reasons that I found it silly he was placed so low. He is still more of a bruiser than he is a tank but he has much better peeling and control than the others in that tier.
Volibear - Placed slightly higher in the tank tier list as Hecarim has fallen and Volibear just has much stronger peeling than originally given credit for.
Xin Zhao - He is still a pseudo-initiator but he's feeling much stronger in the assassin meta than in the previous one. He is still not an assassin helper like Vi is and he's still a poor man's Jarvan but he is able to protect teammates from dives and can disengage hard for his team (what is required in this meta). He does this while dishing out strong amounts of damage, being versatile and a beastly ganker early. He went up in the tank tiers.
Hecarim - He's currently in a free fall. He's fallen from his high perch of the bruiser list and may continue to fall even further. He's too selfish of a jungler and too greedy. He requires too much gold to be reasonable and can be shut down insanely easily now.
Lee Sin - He's a bit of an assassin himself. His assassination powers dwindle as the game goes on but he transitions into a bruiser or beefy support. The amount of skill required to play him is immense but his payoffs are well known. He is a playmaker and definitely strong in almost every meta - especially in this assassination meta thanks to his ability to catch people easily and set up ganks.
Shaco - Lowered in the fighter tier lists simply because he's outdone by everyone else in tier 1 - yes even Jinx.
Kha Zix - Went up slightly higher in the fighter's list as pure damage Kha Zix is still very strong albeit he lost a lot of his former utility and farming speed. It took awhile but I'm finally seeing Kha Zix again.
Vi - She didn't receive any changes or anything but that doesn't mean a champion cannot rise in the tier lists. Currently her "one trick pony" role is actually very strong. While the tier list doesn't take everything from the competitive scene, assassins have become ridiculously prevalent that Vi has been seeing more play in all forms of play (competitive and non-competitive). She is a champion that can both assist her assassin teammates in killing someone by pinning them down long enough for them to be nuked down. At the same time, Vi is also very strong at grabbing the enemy assassin and getting them killed. Most assassins are very slippery but Vi is able to hold them down just long enough for them to be chain cced and bursted down.

Udyr - Went lower in the bruiser list mostly because, while very strong in solo queue, the situations where he is a valuable pick for his team are very rare. His true power is only realized when he is able to get away with shenanigans or obtain a gold and level advantage over his opponents. His turtle stance is overpowered though.
Warwick - He was simply too high in the bruiser list. He is simply outdone.
Aatrox - I don't know what else I can say about this champion that I haven't already said. his ability to simply be too useful is what is bringing him up higher in the tank and bruiser list. He has an infinitely easier time jungling than most champions, he has very strong ganks early along with high damage, he's an insane duelist, he has Malphite's ultimate on his Q, he scales insanely well, versatile builds, low cooldowns and a free guardian angel. He's just too useful albeit he's very gold and level starved. Did I mention he's very strong in skirmishes and farming to the point where it can make that almost a moot point?
Olaf - He is different. The video should contain this.
Jinx - She is actually a very competent jungler. She can exist better in a lane of course but she currently has too much going for her. Steroids are strong for junglers especially those that increase damage potential like attack speed. Her natural attack speed is high enough that it can prevent the monsters from resetting and thus can attack them from a distance where they can't even attack her. She obviously does not have any mobility and can't duel other junglers as well as she needs to and would die to a breeze if caught but she has a ridiculous amount of utility. Her utility immediately makes her a strong contributor to ganks and fights. Her W alone is a ridiculous skill as it has high range, gives vision, is a skill shot and is a crippling slow. Her snares cover a large area, also give vision and trap someone for quite awhile along with also having respectable range. Her ultimate is a very powerful nuke as well - plus it's global. She pushes towers down like a beast and can work with her lanemate to tear down a tower after a gank. I do firmly believe she is better than the fighters below her. What works largely in her credit is that she is RANGED. If she was melee she wouldn't be receiving such praise but the fact that she has range makes her both unique AND gives her better transition into team fights as a glass cannon - the other fighters tend to explode in team fights.
