You can also break a power gamer into a couple of categories...
The minimaxer... Who uses 'the math' to figure out exactly what it will take to 'win' an encounter/war/whatever...
and
The manipulator... Who is, as the name implies, working the social angles to 'win' an encounter...
You see a lot of minmax talk in the forums...from dev. and players. You normally see a social aspect post go unquoted and commented on.
The result is you have a game being developed by mechanics/numbers people that leans to favor those people. They then try to compensate the balance by using more numbers and calculations...
That is the game balance that is out of whack. We have gone away from this game being a social experiment.
