Back in the early days on QW, when we lanned or played online, anyone facing the wall was off limits. And for the most part it usually worked ( there was no such thing as observer mode)
Now, Several things can happen during a match, including a player getting lagged out.
I have never complained about it as it is a fact of online playing.
We're you guys doing a 2x2 or 3x3? If so,try makign it a bigger match to cover up if someone lags.
Sorry but in my eyes, for my team, I focus on getting the flag and capping. The only tiem I would ever stop if there was a sever server lag that was incredibly noticable that it was affecting everyone - then it would be time to check for a new server.
Reaver, it happens.
Get over it and learn from the experience.
