Rushing is by far the best way to play these smaller maps and cod in general, always favoured it and its always prospered for me

To be honest you'll find yourself going back to a defensive/tactical style once you start playing objective game modes again. Rushing in a game mode where the spawns are erratic is much different then rushing with more fixed spawns. You may find yourself defending two flags at once now, but I don't think you'll change up to be a complete rusher

Best advice i could give is change up your game style depending on the map and game mode because not everything will work for every mode/map such as rushing the enemy team on S&D or in your case trying to be stealthy on TDM

I can't stand sitting still.  I rush 100% of the time and the only time I stop is to call in a killstreak.  For some reason, I feel if I'm just sitting there, all the action is passing me by, or that guy just got a kill and I was going to run that way so that should've been MY kill. 

I can't stand sitting still in this game.  Plus, I really only run with SMG's and to win most gun battles, I need to meet you face-to-face.
