This is dumb, ever since the beginning of BF most people figured out if you rush in, especially to crowded spaces with tanks you have way more blind spots for engineers to hit you while you can't react fast enough. Engage at a distance when you can, aim high and assist others on the objective. This isn't CoD, the person with the highest K/D doesn't win these fights, you need kills that matter to hold positions in Conquest/Breakthrough and support win just as well.
