Why do people feel the need to do everything they can before the finishing blow?

I could concede… I let you get the last blow to say GG. Why are you fucking around playing unnecessary cards, putting energy on random shit and playing support cards and item cards left and right.

If I see you fuck around I’ll just concede and give no Thanks lol. Take the W, stop wasting time.

EDIT: To the people that say it’s because they are afraid they missed something, and want to play optimally, I respect that, however you are not the people this post I about.

To all the people saying I’m wasting their time by not conceding. That may be my mistake, and I might be biased. But do people prefer to win to concede when you had a good close match?? What’s satisfying by that victory lol? Maybe that’s just me then…
