I like it as a last-ditch attempt when you are about to lose the line to an enemy full-on offensive or to exploit a sudden weakness in the enemy line. Granted, i'm far from a pro soviet player.
Perhaps it's your connection? I have a crappy 3G connection and sometimes it freezes when i lose connection. It then reconnects and speeds up the game while i catch up.
I think this feature is great. If the match would just end when i got a temporary connection issue i wouldn't be able to play this game.
I have never had input lag before but yesturday i played three matches and in two of them i had horrible delay. Sometimes up to one second or even more. I lost lots of squads because of it and it sucks bigtime. They really screwed up something with this patch.
