The current state of the Champion Senna
@Riot I have nerfs for Senna. Currently she dominates any lane comp just by the sheer amount of stats she gets and how fast she can snowball in a lane. These notes that I have compiled are in my mind believed to be fair to the champion in question.
Here is my suggestions:
Senna:
PASSIVE - Absolution ON-TARGET COOLDOWN: 4 > 8 / 6 / 5 / 4 (scaling with champion level)
INNATE - WEAKENED SOUL: Senna's basic attacks and abilities on enemy champions apply Mist for 4 seconds. Senna's next attack collects the mist and deals 1% − 16% (based on level) of target's current health Attack damage bonus physical damage. The same target cannot be collected more than once every few seconds.
Enemy champions, large Minion icon minions and large monsters that die near Senna spawn a Mist Wraith for 8 seconds. Epic monsters spawn 2 Mist Wraiths instead. Small Minion icon minions and lesser monsters have a 20% chance to spawn Mist Wraiths, reduced to 5.5% chance on those that Senna kills. Senna can basic attack a Mist Wraith to destroy it, gaining Gold 3 and collecting its mist.
ABSOLUTION: Each stack of mist grants Senna Attack damage 1 bonus > ATK Range from 25 to 15 attack damage. For every 20 stacks, Senna also gains Range 25 bonus > range and 15% critical strike chance. Upon exceeding 100% critical strike chance, Senna converts 35% of the excess into life steal. Additionally, Spellthief's Edge item-line grants adaptive force instead of Ability power.
RELIC CANNON: Senna does not gain Attack damage through growth, her basic attack wind-up is only reduced by 0.6% per 1% bonus attack speed, and her critical strikes deal only (65% + 16.25% + 16.25%) AD bonus physical damage, but her basic attacks deal 20% AD bonus physical damage and grant her 10 / 15 / 20% of the target's movement speed as Movement speed icon bonus movement speed for 0.5 seconds.
Q - Healing: 40 / 60 / 80 / 100 / 120 (+ 40% bonus AD) (+ 25% AP) > 30 / 50 / 75 / 100 / 120 (+ 35% bonus AD) (+ 25% AP) PHYSICAL DAMAGE: 50 / 80 / 110 / 140 / 170 (+ 50% bonus AD) > 70 / 115 / 160 / 205 / 250 (+ 50% bonus AD)
TARGET RANGE: SENNA'S Range ATTACK RANGE EFFECT RADIUS: 1300 WIDTH: 130 / 260 CAST TIME: X / X (BASED ON BONUS ATTACK SPEED) COST: 70 / 80 / 90 / 100 / 110 MANA COOLDOWN: 15
W - PHYSICAL DAMAGE: 70 / 115 / 160 / 205 / 250 (+ 70% bonus AD) > 50 / 80 / 110 / 140 / 170 (+ 65% bonus AD)
After a 1 second delay or when the target dies, the Black Mist spreads out of the target, rooting them and nearby enemies for a few seconds.
ROOT DURATION: 1.45 / 1.65 / 1.85 / 2.05 / 2.25 > 1.15 / 1.35 / 1.65 / 1.85 / 2.05
TARGET RANGE: 1175 EFFECT RADIUS: 280 SPEED: 1200 COST: 50 / 55 / 60 / 65 / 70 MANA COOLDOWN: 11
E - ACTIVE: Senna surrounds herself with an aura of mist for a duration. The mist grants camouflage to Senna and allied champions inside, as well as a WRAITH FORM that lasts for the remaining duration. Senna's basic attacks and abilities will briefly break her out of camouflage.
STEALTH DURATION: 6 / 6.5 / 7 / 7.5 / 8 seconds > 5 / 5.5 / 6 / 6.5 / 7 seconds Curse of the Black Mist WRAITH FORM: Gain Movement speed icon 20% bonus movement speed and appear as an obscured wraith to enemies beyond 150 units. Performing a basic attack or casting an ability removes Wraith Form, which cannot be regained for 2 seconds.
R - ACTIVE: Senna fires two beams of spectral light in the target direction, one granting sight in a broad area, the other dealing physical damage to enemy champions hit and afflicting them with Mist.
PHYSICAL DAMAGE: 250 / 375 / 500 (+ 100% bonus AD) (+ 40% AP)
SANCTUARY: Senna and allied champions caught in any part of the area are shielded for 3 seconds.
SHIELD: 120 / 160 / 200 (+ 40% AP) (+ 1.5 per Absolution Mist collected)
I feel these nerfs are very fair to the champion in question. She currently gains powerspikes way too early into the game and just snowballs from there. Thank you for taking the time to read this.
Also to mention the hidden passive/quest she has whenever she faces off against thresh. I think the idea is very cool and super fun. However taking all of Thresh's stacks away from him that he worked for is absolutely absurd. He then loses Armor and AP permanently and Senna gains it all. If this mechanic is intended to be kept, leave a way for Thresh to gain them back and/or take mist from Senna in the same way. Either that or remove the mechanic entirely and change it to a gold gain from the quest.
