One Question that has been on my mind is what classes are favored over any other and why. This applies to any game that allows charter/ class creation or an option to play the game a certain way. Like Modern Warfare 2 multi player you can create a class like a sniper class or in Team Fortress you can be a medic or scout.

My personal chooses are to be sneaky, be so fast that running like a little !&$#* is usually a valid option, or snipe from a distances.
