WoD Dropping.

[kiotsukete]

The Puff of Darkness isn't incentive enough to stay until the end?

No, it's not. Because super low drop rate + rolling vs 7 others = not worth it for a mere vanity item.

Back when ST was first introduced, it was worth staying all the way to the end even if your preferred item didn't drop because at least you were guaranteed a 1/8 chance to win a sand and/or oil.
So my prediction is that this trend will continue until twines and/or coats are added to WoD. (Which I wish SE had done rather than add them to hunts.) Or, they could implement truly randomized loot tables where any piece of gear can drop from any boss.

But honestly, I wonder if leaving early is really that big a problem. I've seen lots of people (usually DPS) do it over several WoD runs, and a rep always pops in on the way to the next trash pull. If it was a tank or healer that left, we may wait a little longer but I don't begrudge them for it. As I'll admit to even doing it a few times myself.

My reasoning is: lots of people are gunning for drops from later bosses. By leaving early, I just made somebody's day who queued hoping for an in progress run.
