Monty is one of my personal favourites in GBs. In GB you know the enemy is coming, just not when. Then you slap them down, and move to the next. However, I feel that Monty in WaW is at an extreme disadvantage. The high angle, short range combo negates any rushing. And in WaW, not many are dumb enough to rush a Monty with no reload cap. So all you can hope for is a deadlock until someone (hopefully not you) makes a mistake.
