Yes. Some common drops ONLY drop for your main class even, like low level PA disks and 1-3* weapons. There's a slight bonus to rares for your class as well, but it's not quite as noticeable.
Have you been playing games with wider FoVs? I blame that as the main reason PSO2's camera feels so close. There's only 2 zoom levels, you might be zoomed, in, but I'd need a screenshot to see.
