💡Champions to Watch This Week

• Notable Buff Champion: Senna → Stumbled in ADC due to the soul generation nerf, but bounced back in Support with a +1.51% win rate increase. With a lower ban rate and a perfect synergy with ranged damage items, the "gunshot in the dark" rings out again🔫✨ Soul harvesting, this is a surplus😎
• Notable Nerf Champion: Yone → Win rate -2.19%, pick rate -0.47%. With the tank/poke meta blocking his engage angles, even his two swords are useless. "Bro, no matter how much 'fate' is on my side, I can't cut through this..." 🗡️🗡️🥲

TOP

   Compared to the data from two weeks ago versus one week ago, the champion with increased indicators, Riven, saw its average win rate increase from 51.58% to 52.49%, its average pick rate decrease from 3.21% to 3.20%, and its average ban rate decrease from 0.11% to 0.10%. Riven's combat indicators slightly improved, including KDA (6.27/5.98/4.44 → 6.49/6.02/4.46), gold (11,518.9 → 11,596.2), and kill streaks (3.05 → 3.12), boosting her win rate. Although Riven was not directly targeted in Patch 25.12, the buffs to Aatrox and Mordekaiser strengthened the teamfight-oriented meta, indirectly benefiting her.

On the other hand, the champion with decreased indicators, Yone, saw its average win rate decrease from 47.21% to 45.02%, its average pick rate decrease from 5.45% to 4.98%, and its average ban rate decrease from 0.95% to 0.89%. Yone's KDA (5.10/6.78/4.20 → 5.30/6.91/4.34) and kill streak (2.32 → 2.26) indicators worsened, reducing his combat efficiency. With crowd control tanks like Shen and Rammus still applying pressure, and ranged poke champions like Yorick and Neeko receiving buffs, his engage angles were limited — these meta disadvantages appear to be the main causes of his win rate drop.

JUNGLE

   Compared to the data from two weeks ago versus one week ago, the champion with increased indicators, Zac, saw its average win rate increase from 49.48% to 50.87%, its average pick rate increase from 4.32% to 4.54%, and its average ban rate increase from 0.37% to 0.38%. Zac's teamfight contribution indicators broadly improved, including KDA (5.18/4.80/10.45 → 5.27/4.88/10.62) and damage mitigated (41,732 → 41,929), boosting his win rate.

On the other hand, the champion with decreased indicators, Vi, saw its average win rate decrease from 49.33% to 48.39%, its average pick rate decrease from 8.65% to 8.15%, and its average ban rate decrease from 1.02% to 0.92%. Vi's core sustained damage was weakened in Patch 25.12, with W - Denting Blows' max health damage scaling reduced from 4/5.5/7/8.5/10% to 4/5/6/7/8% and bonus attack speed reduced from 30-60% to 30-50%, which appears to have lowered her win rate.

MID

   Compared to the data from two weeks ago versus one week ago, the champion with increased indicators, Diana, saw its average win rate increase from 49.43% to 50.48%, its average pick rate increase from 4.85% to 5.14%, and its average ban rate increase from 0.68% to 0.71%. Diana's KDA (7.28/6.21/5.65 → 7.37/6.32/5.68), kill streak (3.35 → 3.38), and damage dealt (21,627 → 21,815) all slightly increased, indicating steady improvement in combat contribution.

On the other hand, the champion with decreased indicators, Twisted Fate, saw its average win rate decrease from 52.55% to 51.86%, its average pick rate decrease from 19.34% to 18.23%, and its average ban rate increase from 5.61% to 8.99%. In Patch 25.12, his E bonus attack speed (10-50% → 15-55%) and R cooldown (180/150/120s → 160/130/100s) were buffed, causing his ban rate to spike. However, his KDA (4.42/5.24/8.45 → 4.48/5.42/8.55) and win rate decreased, suggesting the buffs did not translate into actual game results — this appears to be the reason for the decline.

ADC

   Compared to the data from two weeks ago versus one week ago, the champion with increased indicators, Samira, saw its average win rate increase from 50.86% to 51.07%, its average pick rate increase from 4.72% to 5.35%, and its average ban rate increase from 0.48% to 0.57%. Samira's KDA (9.72/6.44/5.51 → 9.98/6.56/5.51) and gold (13,162.5 → 13,236.7) increased, and in Patch 25.12, the movement speed buff to her passive and the Q damage increase (0/5/10/15/20 → 5/10/15/20/25) directly benefited her.

On the other hand, the champion with decreased indicators, Senna, saw its average win rate decrease from 50.85% to 49.91%, its average pick rate decrease from 13.47% to 10.21%, and its average ban rate significantly decrease from 7.14% to 4.78%. Senna's KDA (4.92/5.00/10.79 → 4.99/5.17/10.94) remained stagnant, and in Patch 25.12, the soul generation chance per minion kill was reduced from 14% to 10%, making the downward trend prominent.

SUPPORT

   Compared to the data from two weeks ago versus one week ago, the champion with increased indicators, Senna, saw its average win rate increase from 46.77% to 48.28%, its average pick rate increase from 3.08% to 3.12%, and its average ban rate decrease from 6.60% to 4.34%. Senna's core indicators, including KDA (2.90/6.01/12.27 → 2.97/6.09/12.38) and kill streak (1.31 → 1.34), generally remained stable, while only her win rate rose. Despite the nerf in Patch 25.12 reducing the 'soul generation chance per minion kill' from 14% to 10%, the lower ban pressure and synergy with ranged damage item builds managed to boost her efficiency.

On the other hand, the champion with decreased indicators, Alistar, saw its average win rate decrease from 50.78% to 49.92%, its average pick rate decrease from 8.60% to 8.49%, and its average ban rate increase from 0.47% to 0.54%. Alistar's KDA (1.60/5.92/13.42 → 1.63/6.05/13.50) and damage mitigated (25,362 → 25,643) remained nearly unchanged, but his death count slightly increased and win rate dropped. With no direct changes to Alistar in recent patch notes, the buffs to other melee tank supports appear to have reduced his relative attractiveness.
