Riot Games is rolling out a significant rework for Senna in Patch 14.16, fundamentally altering how the champion scales and performs in the late game. The changes shift her damage output from attack speed to critical strike chance, while dramatically enhancing her healing and shielding capabilities. This update is designed to align Senna's kit more closely with her unique passive and push her toward a supportive, crit-focused playstyle.

Stat Scaling Overhaul: From Attack Speed to Critical Strike

The core of Senna's rework lies in her stat growth. Her attack speed growth is being reduced from 4% to 2%, a significant nerf that discourages building attack speed items. To compensate, her critical strike chance growth is increased, making crit items like Infinity Edge and Rapid Firecannon more attractive. This change directly ties into Senna's passive, which grants bonus attack speed from collected souls, ensuring she still scales into the late game without relying on attack speed purchases.

Enhanced Healing and Utility on Q and Ultimate

Senna's Q ability (Last Embrace) receives substantial buffs to its healing and slow ratios. The heal's AP ratio jumps from 30% to 40%, while the AD ratio is removed entirely, signaling a shift toward AP-heavy builds. The slow ratio increases from 10% to 15% per 100 bonus AD, making her crowd control more impactful. Additionally, the Q heal's AP ratio is boosted from 40% to 80%, positioning her as a potent healer in compositions with AP supports or mages.

Her ultimate (Relentless Hunter) also sees improvements, with the base shield AP ratio and Mist scaling on the shield both increased. This makes her ultimate more effective at protecting allies in team fights, especially when paired with high-AP champions. The combination of these changes suggests that Senna will be a stronger hybrid support and damage dealer in the mid-to-late game, particularly in AP-heavy compositions.

Key Changes at a Glance

  • Attack speed growth reduced from 4% to 2%

  • Critical strike chance growth increased to compensate

  • Q heal AP ratio increased from 30% to 40%

  • Q heal AD ratio removed entirely

  • Q slow ratio increased from 10% to 15% per 100 bonus AD

  • Ultimate shield AP ratio and Mist scaling increased

Implications for the Meta

These changes position Senna as a more versatile and support-oriented champion. The emphasis on critical strike chance and AP scaling means that players will need to adapt their builds, moving away from attack speed items like Guinsoo's Rageblade and toward crit items and AP support items. This could make Senna a top-tier pick in compositions that rely on AP damage dealers or mages, as her enhanced healing and shielding provide significant team utility.

The rework also aims to make Senna more effective in the mid-to-late game, where her scaling from souls and crit items will shine. However, the reduced attack speed growth may make her early game weaker, requiring players to focus on collecting souls and building crit items to reach her full potential. Overall, this update is a significant shift for Senna, and players should expect to see her in a new light in the upcoming season.
