I'm new to planetside, but even as a complete newbie I could tell there were a lot of people who have NO IDEA what they are doing. This mostly applies to situations that are unique to Planetside like bringing down shields and finally taking bases etc, but still the overall lack of understanding was pretty damn evident.
WATCH THE TRAINING VIDEOS it has a link to in the launcher. At least the middle ones from spawn system to base layouts. They help a lot.
