Ekko vs Diana
So as a Diana main (played her almost exclusively to hit Gold last season), I am wondering about Riot's logic for Ekko's kit. He literally can do everything Diana does (better arguably) and then some. Let's take a look at skills:
EKKO Z-Drive Resonance (PASSIVE) Every third stack (attack or skill) deals 15 + (12 × Ekko's level) (+70% of ability power) bonus magic damage and saps the target's movement speed by 40 / 50 / 60 / 70 / 80% for 2 / 2.5 / 3 seconds. If the target is a champion, Ekko also gains the same percentage of movement speed for the duration.
Timewinder CD: 11/10/9/8/7 Cost: 60/70/80/90/100 Mana Range: 1075 Ekko throws a device that deals 60/75/90/105/120 (+20% Ability Power) magic damage to enemies it passes through. It expands into a slowing field on the first champion hit, slowing everything inside by 32/39/46/53/60%. It then returns to him after a delay, dealing 60/85/110/135/160 (+60% Ability Power) magic damage to all targets hit upon return.
Parallel Convergence CD: 22/20/18/16/14 Cost: 30/40/50/60/70 Mana Range: 1600 Passive: Ekko's basic attacks deal bonus magic damage to enemies under 30% health equal to 5% (+[2% Ability Power]%) of their missing health (max 400 damage vs. minions and monsters). Active: After a 3 second delay, Ekko creates a short-lived chronosphere at the target location that slows enemies who enter by 40%. If Ekko enters the sphere, he will detonate it, gaining a shield that absorbs up to 150/195/240/285/330 (+80% Ability Power) damage for 2 seconds. Enemies caught inside are stunned for 2.25 seconds.
Phase Dive CD: 15/13/11/9/7 Cost: 40/50/60/70/80 Mana Range: 325 Ekko dashes a short distance in the targeted direction. His next attack will deal 50/80/110/140/170 (+20% Ability Power) bonus magic damage and teleport him to his target.
Chronobreak CD: 110/90/70 Cost: No Cost Range: Self Makes Ekko invulnerable and untargetable, and teleports him back to wherever he was 4 seconds ago. Ekko heals himself for 100/150/200 + 20/25/30% (+[3% Ability Power]%) of the damage taken over the last 4 seconds, and deals 200/350/500 (+130% Ability Power) magic damage to all nearby enemies on arrival.
DIANA Moonsilver Blade (PASSIVE) Diana has 20% increased Attack Speed. Every third strike cleaves nearby enemies for 20 / 25 / 30 / 35 / 40 / 50 / 60 / 70 / 80 / 90 / 105 / 120 / 135 / 155 / 175 / 200 / 225 / 250 (+80% of ability power) additional magic damage.
Crescent Strike CD: 10/9/8/7/6 Cost: 55 Mana Range: 830 Unleashes a bolt of lunar energy in an arc dealing 60/95/130/165/200 (+70% Ability Power) magic damage.Afflicts enemies struck with Moonlight, revealing them if they are not stealthed for 3 seconds.
Pale Cascade CD: 10 Cost: 60/70/80/90/100 Mana Range: Self Creates three orbiting spheres that explode on contact with enemies dealing 22/34/46/58/70 (+20% Ability Power) magic damage. Lasts 5 seconds.Grants a temporary shield that absorbs 40/55/70/85/100 (+30% Ability Power) damage. If the third sphere detonates, the shield increases by 40/55/70/85/100 (+30% Ability Power).
Moonfall CD: 26/24/22/20/18 Cost: 70 Mana Range: 450 Reveals and draws in all nearby enemies and then slows them by 35/40/45/50/55% for 2 seconds.
Lunar Rush CD: 25/20/15 Cost: 50/65/80 Mana Range: 825 Dashes to an enemy and dealing 100/160/220 (+60% Ability Power) magic damage.
Let's assume Diana and Ekko are both lvl 18 with roughly 800AP.
We will start with what a thrid hit of passive deals. Ekko's would deal 791 (15+(1218=216)+560(80070%=560)) and has the speed leech. Diana's passive is an AoE cleave that would deal 890 (250+640(800*80%=640)) to all nearby enemies.
Ekko's Q does 280 (120+(80020%=160)) damage going out and 640 (160+(80060%=480)) so potentially 920 damage plus 2 stacks of his passive. Diana's Q does 760 (200+(800*70%=560)) and does not stack her passive.
Ekko's W has an execute passive that would deal 21% (5%+16%(8002%)) of a sub 30% target's missing health. Example: a 2500hp champ would have 750hp at 30% and this passive would deal 367.5(175021%) damage per hit. Ekko's W also has an active that after a 3 second delay cause a field that slows enemies within by 40%. If Ekko steps into the field it would detonate giving him a 970(330+640(80080%)) HP shield for 2 seconds AND stuns any enemies inside for 2.25 seconds. Diana's W would deal 230 (70+160(80020%)) per 1 of 3 orbs for a potential total of 690 damage while also shielding her for 280(100+(80030%)) or 560 (2802) HP if she detonates all 3 orbs.
Ekko's E is a Dash and a Gap Closer. The Gap Closer also deals 330 (170+160(800*20%)) and procs any on hit effects. Diana's E is a close range vacuum and 2 second 55% slow.
Their ultimates are very different from each other but for the intent of this article we will just go over the damage (and for Ekko, healing) portions without explaining any other part. Ekko would deal 1540 damage in an AoE (500+1040(800130%)) and heal himself for 200+55%(30%+24%(8003%)) of hp lost in previous 4 seconds. Example Ekko has 2500 hp and took 1800 damage over the past 4 seconds. His ultimate would heal him for 1190(200+990(180055%)). Diana's ultimate would deal 700(220+480(80060%)) and if Moonfall from Q is on the target, the CD is reset.
Now to skill combos and potential burst damage. Assuming no MPen and no MR on target.
Ekko could deal 920 with his Q hitting twice, E into the target for 330 and proccing his passive for 791. If his ult is in range he can use for another 1540 damage. That is a potential 920+330+791+1540= 3581 damage using 3 skills, not including his W's passive if it procs.
Diana's all-in burst combo of W>Q>R>R would deal 230-690 from W, 760 from Q, and 700 for each R. Assuming all 3 orbs explode she would deal 690+760+700+700= 2850 damage using 4 skills and would still require several attacks to proc her passive on the target.
TL:DR
Ekko can deal almost 1000 more damage in his combo, using 1 less skill. Also his skills proc his passive(s) and Diana's do not.
Thanks for taking the time to read this giant wall of text. Like if you agree that some love needs to be shown to our Lady, the Scorn of the Moon!!
