If he was afk and you attacked him, he could have killed you. That's par for CF. It gets a lot worse. You can have everything in the world, and boom. It's gone. Take nothing for granted in CF. You will die with only a name. Its a harsh world, no matter what you have, you will have to work to keep it. Roll with it. Adapt, immerse, enjoy. Get angry, and use that anger to relish in victories to come.
