I am pretty confident that you will find that any player who tries to go only for the biggest and best in this scenario, is likely to fall sooner than one who remains adaptable, and is as creative as possible in their application of force.
Changing from the default settings WILL create different dynamics. However, it's a bit silly to make the assertion that while the game is fairly well balanced, that it is balanced out in such a way that altering the settings (in ways that are meant to be able to be altered) in some way wrecks the game as a whole.
I would consider that more of a personal problem, than a flaw in the system. Just as it seems that my thoughts about the map, are personal issues.
