Laser-Chain and Patch can both take out the weak vehicles easy. The MRL, Hummer, MOb Art, and Buggy will go down fast to one of these characters, and with the high rate of fire it's easy to pour a steady stream of damage into them.In fights versus infantry anyone playing LCG or Patch can kill another character fast with a steady stream to the head. Lesser characters will die in under 5 seconds from full health if you land all your shots to their head. Snipers are the easiest to kill because you can come at them from the side or back and unload a whole clip into them in seconds. All too easy.
Play whatever class makes you happy, but there's no need to rag on the classes you don't like because I guarantee someone can own you with them. Heck, a basic soldier can own any class if the player is better.
