Regarding Immortals, we talk a lot about the Huni/Reignover duo and how they play together. I take a look at early kills involving jungler to see how much Reignover is playing around his toplaner. So, to sum up: 35% of kills involving Reignover before 15 min are against the enemy toplaner.

Stats are from the half split (Summer Split). You can find more stats about Immortals here: Immortals stats
