Right, and that always pissed me off about FH and other games that do it. If a map favors one side over the other, it's not a well designed map. To my way of thinking, the ideal map is one that either team can win.
There was a map in RO: Ost that was, in my opinion, the most perfect map I've ever played: Berezina. It was an attack/defense map. The trick for the Russians on defense was how many reinforcements they'd spend defending weaker positions vs. falling back to more defensible ones. For the attacking Germans, the trick was in exploiting speed and overwhelming enemy defenses with a coordinated attack. Neither side had it easy throughout, although some parts were easier for one side or the other. It was perfectly balanced, though.
I wish more games did that sort of thing.
