Once when I was playing with my guild in HoH, we were doing the 6-team battle and were one of the last 3 teams left. We were facing two French teams (they were both speaking French and from Europe, so we assumed they were French) who decided to work together and gang up on us because we were American (or that's what I got from their convo - I wasn't able to decipher most of it but I could understand enough to realise we were going to be hit hard). Well they both attacked with suprisingly good timing, but to our suprises, we held both of them off and killed enough of their teams that they backed off. I guess it was a good thing we were trying out a defensive build

. Unfortunately we lost about 5 minutes later because no one was doing anything so we decided to attack. They both ganged up on us again and we dropped. It was still fun though.
Oh, and just today I beat the Gates of Kryta mission alone after all of my team quit. Good thing I had done the mission 50 times over so I knew what to do.
And one last thing - Beating the last mission in the game with henchies after failing 3 or 4 times with human teams because we suffered a lag spike in the
exact same spot every time.
