I like the variable damage rates (300 vs. 331) of all the legendary and exotic weapons. It makes every players character more unique. It's no fun when everyone has the same weapons and damage rates. I have many 300 max damage weapons that I use ahead of a 331 max damage weapon. There is more to a weapon than it's DAMAGE number. How about the elemental damage attached to a bevy of weapons? I have a Payback SOS at 331, but after maxing it out I went back to FB and VoC just for the sake of the Arc and Burn. The Culling at 300 is still awesome too.
