About 2 or 3 hours ago, i wanted to do W2.
On Sloth first kill, no one got loot. Then we killed Sloth again and most of us got loot.
So we went on with the Trio and killed it, again no one got any loot. Then we decided to disbandon our undertaking.
It is to be noted, that we did no first attempt kills. I mention this as someone said that he heard only first attempt kills would give loot.
