Thats probably a good strat. I definitely get "kill fever" and can get too focused during firefights and let people flank me and such. I think two of the best things with squads is to stay relatively close together so you can fight together.. The teams I've done well with would take good house positions so we could ambush people we saw... That and just a little communication keeping everyone informed where we are being attacked from. Thats been the big difference for me on the teams that win.
