Do not like the aggro radius of mobs it's way over blown. I rarely stop to gather in the desert maps because it means what feels like 10 minutes worth of fighting. They also respawn too fast. Less aggro radius, longer respawn rate, or just less mobs in general would be nice. Hard to enjoy exploring when you can't stop to enjoy the scenery. Do not like how to acquire the exotic weapons for the elite specialization collections. Drop rates are way too low.
