I love how adaptible kha'zix is. Like his lore and design are incredible, but the gameplay suits him perfectly. He can build a wide variety of items, take a wide variety of runes, and evolve any of his four abilities. From the beginning of champ select you're already thinking about what the ideal approach to the game is and you get rewarded for it. He's a slow clearer and not a great early ganker, so he really rewards you for being creative with your pathing and knowing your matchups. Because of his isolation mechanic, as the game goes on you have to predict where the enemy is going to be to catch them out of position, you can't just blow someone up in the middle of three or five people like other assassins.

Once you really get rolling to the point youre one shotting people all over the place, you usually feel like you got there because you were smarter than the other player, and that's pretty cool
