If it's obvious to enough people that a team is tanking, then do something about it. Otherwise this whole conversation is kind of pointless. If it's an issue, address the GM and if they don't have a good excuse, then go from there.
Also, the line between rebuilding and tanking can get blurred sometimes, like what Mr. Hokeypants brought up.
