Voted no as expected.
I don't see the point of option no 3 - both ways work.
How can both ways work if the person in front of you suicides?
At least on rolls you have a chance to win something in that moment and it's faster also.
Also, you compete against 3-4 people most of the time so you have theoretically 25% chances or even higher.
And another point. Due to the lack of interest of skirms in the kin (many people have their chars already geared) in many cases we will need pugs and the suicide point fails here.
Another thing. Most people these days want the scales. Those people probably won't suicide and might go for pugs instead of joining kin runs just for the fact that they can have the chance of rolls.
Not speaking about me on this, as I am always willing to help, even though with 3 chars I go on pugs also cause I can't bring everyone in kin runs.
Probably the people who will suicide the most will be the ones at the bottom of the list which will have nothing to lose basically.
Edit: All the comments are not related to my luck streak from now. We always used rolls in the kin, even when I wasn't winning so much
