Hi, 
I am a level 22 Hunter and recently upgraded my gun from this: 
 
  
to this: 
 
  
As you can see it has more base damage and is faster. 
But now please compare what the character damage display shows for both weapons: 
  
1. With Silver-plated shotgun (the old gun): 
 
  
2. With Double-barreled Shotgun (the new gun): 
 
  
It shows more DPS as expected but less base damage and I do not understand why. 
The only active buff is Aspect of the Hawk, I relogged, restarted the client and deleted WDB folder, it still shows the same. 
Can someone explain this to me?
