i saw couple of times people who when f.e. arkanian boots drops they strangly have 61s mods in them end rest of gear mix of 69/72.
or story from yesterday,not gf but pug toboro. fury drooped mainhand we roled ,some guy won,got loot ,but when i inspected him he had no mods in his mainhand,
People in this game go to strange lengths to got loot, forgetin they didn't solo killed boss,but that was team effort .
That's why its better to have free roll rather than need on pug runs - so ppl don't have to gimp their gear for fear of not getting drops due to not "needing".
