Support and adc are the most stressful positions in the game
Probably because you play with someone else. Playing adc with some guy who's been playing the game since season 6, who proceeds to rush morellos as lux support with heal and flash as he tries to say he doesn't know how to support while maining adc (the class that's always with a support...) or playing support with an adc who doesn't realize their potential/kill ability at the right moments but instead runs 3000km into the back line in an attempt to get one kill.
Supp/adc are very fun roles if both of you are on page. It only takes one of you to be bad for the lane to be crap.
Your partner probably gets titled when you do dumb shit and you probably get tilted when they do dumb shit.
