I'm a casual player. It's impossible for me to advance the only frame I'm interested in playing. I occasionally see some Regenics and head for the watchtower that reports them in SIN. When I get close I am notified by the ever helpful Aero that there is a squad thumping nearby. So I check the map again and head for the squad. My waypoint invariably disappears when I'm halfway there, telling me the squad has sucked that vein dry. It's impossible for me to advance the only frame I am interested in playing, and I'm pretty frustrated by it.
