Every CTF mode, the only mode I play so every game session in other words, is the same with me. Play path finder, snipe base turrets/radar. Die by player defenses to small/covered up to see. Or lucky enough there aren't any/allies or I got them. Take flag, run circles around the base to avoid enemy fire hoping my allies get our flag back. It's complete luck as to the competency of my allies to do so. 50/50 as to whether I'll cap it.
Continue to rage at team.
Rage makes me switch to camper technician. Placing turrets, repairing defenses, and if nothing else, shooting at guys near out base. I do this with "success". That is, my in game score is impressive but the fun factor is bad. Realize I'm just camping and not having any challenge thrown at me and quit.
Bad teamwork and repetitive, end all strategies are what kill it for me.
