Regardless of the character I play, this almost always happens. I like all of the main three, and it seemed just a couple days ago that the turn-based nature of the game was making it less toxic than other fighting games. But all of the characters have moves that often make the other person just say "fuck this" like opening with lightning strike or extending your combo with quick slash. I always stick around just because I want to see what crazy thing will happen next, and I thought that was the main draw of the game, but apparently not. I'd rather just play the game with friends now if everybody else will quit out over a 3 hit combo, and I'm ok with that being the scope of the game's multiplayer since its so experimental.
At least the game doesn't punish you for disconnecting other than mocking you in front of the other player, I much prefer that to games that ban you for having bad internet.
