I went to do a conflict site for rep yesterday at Bolinas Smeltery and saw one other person there. The threat level was at 10 so I assumed it was a higher EGO person such as myself. I killed one enemy and then proceeded to the next site.
I figure it is easier to let him handle the threat level 5 than 2 of us doing it at 10. The other conflict site was empty and I was allowed to complete it at threat level 5 with no issues.
If you see me at a site feel free to tag it and leave. Much easier that way.
