Not sure if anybody else has experienced this or even if its actually a problem.
If I have a gear piece with, for example, a low armor roll. When I roll, each time its giving me the same value. To get a different value I have to roll armor away completely (take skill haste or whatever), then roll again and hope armour comes back with a better stat. So in effect to gain a different value on a stat you have to roll twice to get it? Seems a bit odd and certainly didn't do this pre 1.4.
I'll farm some more credits and test a bit more tonight.

I had this issue as well yesterday. I was trying for a marksman rifle upgrade on a set of gloves but it took about 8 different rolls to get one. The rolls kept giving either the same values for the same item such as +7% critical hit damage but swapped the position in the four different options given or gave the same option for SMG or Assault Rifle. I thought there was supposed to be six options at re-calibration as was only getting four.
While re-calibrating, I wasn't given any option to choose. Logged out/back in and I was able to recal succesfully. I also noticed the amount per recal went up each time, however it was not taking my credits. Also after logging back in those Items had not actually been re-calibrated. Most likely some type of connection error.
