Yasuo has been strong for a while. His ultimate and critical chance are ridiculous; he also works well against most champions that go mid while still having a great team fight presence. Because of how his kit was designed, he’s able to outplay and outscale--Wind Wall is just too good of an ability.
Nidalee moved from a mid lane annoyance to a top lane terror when she was reworked. She’s absolutely devastating when built as AD, and her early levels make her one of the biggest lane bullies in the game. It doesn’t hurt that she’s extremely mobile—making her hard to gank and excellent at split pushing.
Morgana has a perfect kit to make bot lane plays. With a shield that blocks CC and a bind that lasts entirely too long, she is great for winning skirmishes and following up ganks. Her ultimate is also strong, allowing her to initiate with it then land a seamless bind on those it stuns.
Maokai's changes a few patches ago meant to make him a jungler, but it ended up planting his roots top lane instead. His kit is frustrating to lane against and his new damage makes him much stronger. But his real power is in his ultimate and team fight; he’s great at initiating and sticking to a carry.
Tristana defines the word carry. She keeps getting range thanks to her passive which allows her to scale into the late game. Having high range along with an attack speed steroid and a resetting escape means that even if teams lose early game, she can help them turn it around late as she outscales every other ADC.
Braum has a completely broken passive at all stages of the game. To make it worse, the rest of his abilities are incredibly good as well; Unbreakable and his ultimate provide an immense amount of utility. He can carry from the support role, something invaluable in solo queue. Nobody wants to lane against a Braum.
Talon may have a weak lane phase, but he’s really strong as a roamer. His ultimate has a low cooldown and he does tons of damage; he scales well with items and snowballs once he picks up kills from other lanes then becomes impossible to duel. He also has one of the few silences left in the game.
Kha'Zix is going to be nerfed soon, but the main reason he’s so strong is his W change from a few patches ago. Not only do they now give vision when evolved, it’s a 50% AoE slow and it makes his jungle clear very strong. He also maintains great assassin potential thanks to Isolation.
Zed's power lies in his ability to both assassinate and split push. His split push is excellent and he’s mobile along with a great duelist, meaning he can escape or fight those who show up to stop his push. He also necessitates the use of Exhaust and encourages the Zhonya’s Hourglass rush, changing people’s play simply by showing up in a game.
Fizz may have high mana costs, but he’s a ridiculous powerhouse. His potential as a counterpick makes him strong and his burst is nearly unparalleled, especially after the decline of champions like LeBlanc. He necessitates the enemy building MR or else he simply does too much damage, even to popular junglers like Lee Sin.
|Vi is a solid jungler. While she’s only banned in some regions, she remains a top pick that skates the overpowered and balanced line well. Her ultimate has excellent synergy with certain champions like Yasuo. She’s also able to pin down a target in a team fight which works well in this meta where Zed, Talon, and other squishy assassins need to be shut down before they destroy an entire backline in the blink of an eye.|
|Zilean's strength stems from his ultimate. He’s able to hold his own in lane and his double bombs have a lot of utility. His speed up is powerful, especially with certain champions such as Rengar or assassins; he’s able to protect those who have a need to dive deep into the backlines to secure a kill. He works especially well in solo queue because he can help save someone who makes a miscommunication or a bad play with his ultimate.|
|Alistar is the perfect support and a great top laner. His ultimate was changed recently which allows him to tower dive earlier as well as win skirmishes harder since he takes significantly less damage than before at its first rank. His peel and engage potential is superb, especially considering the increased popularity of champions like Zed or Talon who need to stick to a carry to burst them quickly. Alistar can easily be the foil to any burst composition through his combo and utility.|
