I'm confused, are you talking about the experience you earn, or that your squadron does? The squadron exp is pretty limited, but personal exp is kind of insane. It's by far the fastest way I've found to level sub-50, often gaining two full levels and then some per run. My only complaint is the large gap between Brayflox and Stone Vigil where you can't totally optimize your exp, though Brayflox is still pretty significant even at level 40. Admittedly I have access to all of the experience boosting items and generally stop doing squadrons when I run out of rested exp, but still. I wouldn't want to gain it any faster, frankly, because I tend to outlevel the content long before getting enough drops to be well-geared for the next dungeon.
