You can always tell a boxer by the way they walk, lol. Even when I'm on solo I find myself looking behind me and seeing if the teams with me up stairs out of habit.

Man all I can say is level out of the Org/TB areas as quickly as possible. We all have to make sacrifices you know doing what we do. Like I always walk my toons 1 by 1 through Dalaran instead of trying to fight the lag. Lag, getting hung up on stairs or tight corners just try and stay aware.

I know I've gone through half a dungeon before realizing one of my team got hung up around the beginning, lol. That always sucks but I try and keep a better eye on it now too.
