Pentakill Kayle just makes me sad that she's a niche pick at best.
She's always just been an unholy bundle of random stats with no identity beyond 'look at me I'm an Arch Angel-type thing'. At on point she was broken because of her front-end burst, then her ability to abuse AS On-Hit items, and then she just randomly has a bunch of Utility tacked onto her kit.
With Skins like Awther Wing and Pentakill, and how long she's been in the game, Kayle really deserves better than this.
