"TF2 was never intended to be played with FF on. It was an oversight that the convar was left in. It'll be going away shortly."

Новости csnation.net: Team Fortress 2 Updated
An update has just been released for Team Fortress 2. Both clients and admins will need to update because of this release. The changes are set to follow these words.

* Fixed a crash with ATI cards running on Vista
* Fixed a networking problem that could cause a crash certain types of home networking hardware with out of date firmware installed
* Fixed a networking problem that could cause some animation jittering
* Fixed bug causing incorrect .dem files to be written (all files after first .dem file would be corrupted)
* Fixed bug with placement of teleporters that could result in players being unable to move
* Removed mp_friendlyfire cvar for servers. Team Fortress 2 breaks in a number of ways if this is on
* Fixed some truncated strings in the destroy menu
* Spectators can now see all player classes in the scoreboard
* When a round finishes, if there's less than 5 minutes left on the timelimit, the server now goes ahead and switches level right away, instead of going into Sudden Death
* The affinity of the main thread is not set explicitly for dedicated servers. This will properly load balance multiple instances of the dedicated server running on a multi-processor machine. The affinity is still set to CPU 1 for clients and listen servers
* Fixed crash on startup Fixed crash caused by .dlls being loaded from the user's path, instead of from the install directory

You may restart in order to snag this update immediately.

Надо пролезать в инвиз и по стенкам ловить моменты, надо знать карту на предмет обходных проходов. Например 2forts, если в дворике с 2 лестницами поставить 1-2 турели никто не пройдет, но если с крыши моста прыгнуть на балкончик(а это можно скаутом, просто надо потренероваться), то эту турели спокойно обходятся
