Didn't say that.
FOW can be part of the balancing act. Especially when it is in the description. Let me ask you. If you were a ladder player (maybe you are), would you want to be on the end of an unbalanced scenario and have a low chance of victory? A h2h scenario is supposed to be balanced or at least have a statement that says something to the effect "the more experienced player should be such and such side" That's common in the description of some scenarios.
I think the one poster was spoken to in a manor that was as if to say that he was mistaken to play this scenario mirrored. But no one said not too in the description. And for the scenario designer to have to explain tactics is, to me, saying that there is a chance that the scenario might be unbalanced and worthy of the "experienced player" disclaimer. And as previously stated, mirrored play is a way to insure against an unbalanced scenario when playing on ladders.
I'm not try to start an argument. I think we are all trying to give constructive criticism and I would think the scenario designer would be appreciative of that. If, for some reason, he doesn't like constructive criticism that this is the last place to publicly ask for someones opinion!
