Leader (shot caller) or follower?I usually leave that to whoever thinks he's good enough for it, and offer feedback on it. A lot of baron-throws have been prevented this way.
What is more important to you: CS or kills?I'd say that depends on the stage of the game, early on I'd definitely prefer CS, the later the game the better kills are.
Do you prefer grouping early, late or maybe never and play on your own the whole game?I play a lot of top, so I'm either teleporting in or pushing.
Do you play passive or aggressive?Depends on the matchup, usually passive until I know I can outtrade.
Which Lane/Position do you like the most/least?Top for most, people don't depend on you too much and yet you can completely turn the midgame upside down.
Mid for least, you have to depend on so many things, you can get punished really hard for mistakes, not my kinda place.
Who is your favourite champion and why?Rengar - Oneshots, bushes and exploding backlines. (video example of me below)
Shyvana - What I play nowadays because assassins aren't all that much in the meta. She's quite tanky, has decent mobility and can solo the enemy backline if played correctly.
Which champion do you hate playing against?Depends on the matchup, lissandra is the only thing that stands out.
What is the best feeling for you playing LoL?Jumping into a backline and seeing it explode as soon as you touch it or counterganking the enemy jungle for the entire game, about equally satisfying.
Penta kill or winning the game?Winning the game.
