Ahri
Edit: I get that it'd be justified if the Ahri was just simply fed and carried the game off of it but it's the fact that Ahri is just overpowered at her current state AND was doing such things late game where everyone was full build.
Now don't get me wrong, I'm not part of the Ahri circle jerk that just recently sprung up. That said, I always have hated Ahri (alongside with Lux, trynd, etc but this isn't the topic) and I just played a game that confirmed that Ahri is not balanced.
First off let's start off with what Ahri has objectively
Passive - A passive that gives Ahri sustain after she fires off x amount of abilities. Q - A skillshot that fires out and comes back to Ahri. It has true damage on the return and gives Ahri a burst of move speed. W - Three balls that rotate around Ahri that acts as a homing missile to a nearby target(s). E - A linear skillshot that fires out and Charms (taunts) an enemy. R - 3 Dashes the length of flash that is able to casted back to back.
Now let's focus on some key factors in her kit which makes me say Ahri is busted.
Passive - Sustain Q - True Damage - Movement speed W - Homing missile//"not interactive" E - CC/Taunt R - Three dashes the length of flash. Able to be casted back to back. (Think of 3 back to back flashes)
Now you may say, "Well she's a jack of all trades, what's wrong with that?"
What's wrong with this is that all of these abilities do insane amounts of damage, half give insane mobility, one gives CC that many champions are based and built around, and she has sustain in her passive to let her survive or even destroy the laning phase. To top all of this off, these abilities come in fairly low cooldowns with low mana costs and late game she is able to flat out spam it.
Now there IS a reason as to why I made this post just now. It is because I played a game where we faced an Ahri. I was going Yasuo top (hurr durr annoying op champion) and had a TF mid. Now I may have been able to carry this game if it were not for a 1/7 TF @15 minutes but I'm going to get to the point. I was fine with having to face the Ahri and even managed to snag a kill by triple teaming her but lategame there was nothing that could stand her way. Here are some numbers that came at me stemming from the Devil herself - Ahri.
Her Q did roughly 400 damage on the return (I didn't see her initial Q damage but it has to be high)
Her W did roughly 600 damage
Her E did roughly 600 damage
And I did not see her Ult damage.
She bursted me down 100 - 0 dealing 2600 damage within .78 seconds with one rotation of her spells. (okay, to be fair 400 dmg did come from the opposing orianna)
ANYWAYS I'M SLEEPING NOW CUS I'M TIRED BUT I'LL COME BACK TO THIS THREAD IF I FORGOT TO VOICE SOME STUFF. GOOD NIGHT THANKS FOR READING.
and not Visage on a Yasuo, it keeps your AD high while keeping MR and protects you specifically from burst.
3 shots you once you're poisoned though
