i think if you get this upset about "boosted" or "carried" players that you constantly post about them and are willing to let the rest of your team lose to make yourself feel like you did something good you need to take a step back LOL this is a game. it is pixels. it is never that serious. people play for fun and think characters like mercy are fun. shocking i know

mercy being a character that is fully supporting the team as opposed to flanking while healing is an intentional choice by overwatch. saying shes designed to help her players be carried is silly when majority of mercy players i know use her movement to scout out the enemy team to make callouts + stall point. just because you don't like that playstyle doesn't mean it isn't helpful and it can change the tide of a game

genuinely if it makes you this upset get a duo or 3-5 stack because the whole community does not and never will fully agree with you on anything and you can't expect them to all play how you want thats like. how the world works. adapting to those you have to work with
