It is a camping setup. You are absolutely right. I like to hold down the fort. I move if I have to, and not bad against one-on-one matches from medium-long range. People tend to revenge kill a lot, so they end up coming back to me, not giving me a real reason to move around.
I let the Operations decide my loadout.
Right now I'm working on Balls of Steel, Long Distance Relationship, ICU, Clear Skies, and Air Superiority (See my thread on how lame this killstreak is)
