Unnecessarily dragging out a round

There is one thing about DbD that really bothers me. I don't mind it when killers slug. However, it annoys me when they do it during the final two survivors, effectively dragging out the match. One survivor is left downed while the killer spends ages hunting for the other. You help the downed survivor up, they go right back down, and the whole cycle repeats. I was playing with my best friend recently and we ran into exactly this situation; the match dragged on for 20 minutes. You can't just quit the game, because you get penalized for it. And that’s exactly what kills the fun. Please let the downed player bleed out faster. I play both killer and survivor, and even I find it too boring—I don't do it when I play killer.
