Funny thing is, if he *didn't* ragequit, you might've been screwed since I don't think you had any recharges left at the 6th, and he was actually good at countering you. He had no way of knowing, but if he decided to stick around a moment longer to finish it, he might've downed you.
Oh yeah, despite all the sodas I was barely doing damage and my build has no real escape options other than grapple. I was annoying, sure, but not much else than that.
Can't tell if the raider thought you were cheating and ragequit because "winning is impossible" or if they ragequit because your build is a major pain in the ass to fight against. I think it was fairly obvious that was a ragequit, at least. Well, maybe 95% chance ragequit, 5% chance of an internet outage at the worst possible time.
Although you by yourself didn't do much beyond waste the raider's time. Imagine if you had 2 or 3 survivors with the same build. How is the raider meant to stop that?
