There seems to be a lack of transparancy and details in the changes starting from 10.1 . There are errors in 10.1 which was never fixed.
For example, in 10.1, Rifles were nerfed "30%" but upon inspecting the character "stats" , the PVP DAMAGE doesn't reflect the actual nerf. The only way is to actually hit a person in the DZ and compare the damage numbers to what's listed under STATS. The nerf is indeed there.
For TU11 under the PVP section:
Where are all the final pvp modifier numbers for the changes to the pistols, shotguns, rifles, MMR, SMG?
All the info listed are very nebulous. It would help if what you see in the character stats were accurate but it's not. It seems to be manually edited instead of calculated.
