Yep, because you getting 100% accuracy is going to happen.
Not even the best players have over 60%.
Stop making up stupid shit.
A player refusing to switch and being an a-hole will 9 out of 10 times cost you the game.
Its a team game and 1 person not doing his job will usually mean its game over.
You can carry but the enemy team will know and will counter you. Seeing you are one person down they have 2 people to counter your ass which will take your out of play as well.
