In individual pvp, I only lost once - to opti.
I was TVing Kenny and his internet disconnected, causing me to be forced off teamviewer, thus forcing me to literally jump off at Zeon speed because TeamViewer lagged me and became the main window for long enough (stupid tv).
I've lost 5 times in team pvp.
Three because of laggers who attack me with ghost hits because we're not connected, causing every other person in the room to be able to literally pile me when I take a ghost evade hit in mid air.
Two because of actual teams who defeated me (Neo's team and ZomZom's team).
