I came back on to it recently, it seems as I still have skill to be an infiltrator that hurts or a sentinal. My skill is rusty however, such as I used to hit like a monster with the technician's SMG, and the ability to get 200 whatever units easily on most maps. I'm up for a game at most times though :3 I also remember being able to have skill with vehicle management, making the shrike, cycle, tank, and whatever else there is useful and not blow up instantly, I usually get some hit and run damage though.
