Yeah, I wont hold your hand, but I may show you where to go and what to do.
Rushing in BF3 I think is a bad idea. Lurky slow creeping and flanking is the way to get kills IMHO. The fastest way to a point is not a straight line since that leads you through open spaces that everyone can see you from the cover they are hiding behind.
The rule I try to use (TRY since I dont always do it) is the person how spots the oher person first is the winner in this game. I try to put mself in a position to see someone first.
