You know that was US players of 1.0 that demanded them to change the loot system right? We had several player polls and they changed or tweaked from what Us voted for. Everyone didn't like to farm endless every single day same dungeons for drop rates of 1-2% getting to a point of staying sometimes 1-4 weeks without seeing a single DL drop or worse trying to get the speed run chest for body was also other pain, it would take long or super lucky to get them. In my case took me over 400 runs and after 3-4 months to get my corselet for mnk and complete the set so yeah...

So what they decided to do? Make some 100% chance to get a item between 1-2 weeks and being locked for next week.

I could say some more stuff about pros and cons of this but no time to do it now. You got the idea.
