Yes, the 2x damage increased is the main reason. You'd know it's easy to run out of ammo because of the heavy armor enemies become more heavy, so that cause more and more enemies keep survive in an area that cause your whole more dangerous. Excalibur's damage provision/support isn't enough to go for 1H run sur (lack of life support from slower killing speed), thus you see why most ppl prefer Nova than Excalibur. But also ppl prefer Nyx than Excalibur too, Radiation/Chaos could increase whole team's damage (extra damage from the enemies you control).
