I'm sure that this a bit too general but one trend I'm noticing in my replays, especially in my Russian heavies, is that I am dying to backfield TD's after the flank I've been working breaks and I move forward to follow through. I'm getting better about conserving my health and so on but I keep getting ripped apart in the late game. I'm sure there's a lot of factors that go into this. However what are those factors I need to be considering so I can avoid getting mauled while still being effective? What should the general plan be after a flank goes down?
