Same here, i love being the medic or the engineer in battlefield, basically i prefer to support in shooters that i am no good at. Unfortunately taking out air vehicles is the closest i can get to a support role on CoD. I use to play more battlefield 3, but then my main friends that played it stopped, so now i am trying CoD since one of my friends that i usually play with really likes playing it. Simply put a game (even if it isnt the greatest) tends to be more fun if you have a good friend or two to play with.
