I've been watching a few videos by Zeven and a lot of what he does is get his team to do the right thing. His mantra seems to be you need to win one side *before* the enemy win the other.
Is very useful:
I second this. The good players i've seen in game tend to choose a side, 'carry' it and then flank the enemy force for the win. Even in tanks such as Grille 15. They don't bother with the perfect sniping, hulldown etc. positions when those are not on the break through side.
