As we know, patch 10.5 focuses heavily on changes and balancing the top lane as well as some minor adjustments for the jungle champion pool, therefore, the mid lane meta will not see much disruption. This is also considered a stable phase for this area as players have a wide range of champion choices with various playstyles and strategies.
Here are the top 5 champions currently dominating the mid lane meta in patch 10.5:
1. Diana
The mid lane has witnessed the prominent rise of several champions in Season 10, among which Diana stands out the most. Her ability to create outstanding teamfight engagements with E – Crescent Strike and R – Lunar Rush, along with her healing capabilities after taking damage from enemies with the Conqueror rune, has made her a great choice for both early and late game.

Currently, Diana boasts a win rate of 51.43% with a pick rate of 8.86%. In the future, unless she faces any direct or indirect nerfs through runes and items, she will continue to dominate the mid lane.
2. Katarina
From patch 10.4, Katarina has emerged as a phenomenon in the mid lane meta with an astonishing win rate of 53%. Although her skill set offers very little crowd control, her ability to deal widespread damage and her mobility pose significant challenges for her opponents.

Similar to Diana, Katarina’s skill set synergizes effectively with the Conqueror rune, allowing her to heal significantly in the late game. Her ultimate R – Death Lotus is particularly useful against teams with substantial healing capabilities, as it inflicts the Grievous Wounds effect on all enemies hit. Therefore, Katarina is even a great counter-pick whenever Sona or Soraka appears in the top lane.
3. Taric
Taric himself is not a strong solo lane champion, but when paired with Master Yi using the “funnel” strategy, he achieves the highest win rate in the game at 63%. Although his pick rate is not high, this proves that when used correctly, Taric can produce incredible results. His ability to shield and heal hyper carries like Master Yi while still reaching necessary power thresholds with minimal gold makes him one of the best funnel strategy support champions in League of Legends.

With the buff to Blade of the Ruined King in patch 10.5, Taric’s win rate and priority have shown signs of increasing, as the champions he typically pairs with will greatly benefit when facing tanks and fighters.
4. Kassadin
Kassadin’s late-game power makes him one of the most viable mid lane picks, and this remains unchanged in patch 10.5. When Kassadin reaches level 16 and acquires items like Rod of Ages, Archangel’s Staff, and Rabadon’s Deathcap, he becomes an almost unstoppable monster.

Kassadin can also easily escape ganks after level 6 and create map pressure thanks to his roaming ability and terrain traversal with his ultimate R – Riftwalk. When you lack confidence, Kassadin is always a strong choice in the mid lane if you feel it’s hard to survive the early laning phase. Furthermore, there’s always a chance to create spectacular backdoor plays with this champion if used correctly.
5. Cassiopeia
Cassiopeia’s late-game damage against enemy champions and objectives makes her another safe pick in the mid lane in patch 10.5. With just three items, Cassiopeia can help her jungler easily secure Dragon or even Baron.

With W – Miasma and R – Petrifying Gaze, Cassiopeia contributes significantly to teamfights and can turn the tide of battle if used accurately. Additionally, her W ability also makes her an excellent choice against highly mobile opponents like Kassadin, Katarina, or Diana.
