Well, yes. But I don’t think that game really knows a winning team from a losing one. I have a strategy where I intentionally let many of my monsters die in order to win, but the game would probably say that I was losing because I was down a few monsters
I always have full bars when I do pvp, but connection is still unreliable. The server could reset, the power could go out, my router could glitch(which it does often), the game could update and kick me out, etc. Any company owner would tell you that keeping an account online without any disconnects is impossible, regardless of connection.
Need I say more?
