I'm another guy that prefers the modes with objectives. I think these modes tend to require a little of both styles. A tactful team that can constantly hold at least 2 locations in Domination is never going to lose. I'm usually running with randoms, so trying to be tactful is usually an invitation to get flanked and shot in the back, so I spend more of my time assaulting enemy-held positions. I generally end up with a lot more deaths than I'd like, but like someone else said, going on the assault with at least one other dedicated wingman could eliminate a lot of unnecessary deaths simply from not being outgunned by default. I also often turtle up with a heavy shield while playing hardpoont to draw fire and open up distracted enemies to easy team-kills. I have no doubt that this would also be more productive when not surrounded by randoms.
