So with the new patch we can add a weapon from before for appearance only, so when I did this the details show my DPS dropped from over 9000 to 5400, accuracy is showing 10.6% instead of 110.6% yet I have over 2700 in accuracy.
It seams that these changes did not happen to the toon, just the detail screen but now it is hard to tell when making gear changes as the detail screen is messed up.
