There are two main areas the Warsat events spawn. One is right where you spawn. The other one is in the scablands. I would only travel back and forth between these two. Another option is to pair up with anyone (check recruitment) and the two or three of you just drive around, not forgetting the rubicon wastes since I do believe one event spawns there. I used to use the public event tracker, but it has been really off for some time now. I think people keep reporting taken events and it throws the whole thing off. To me, the tracker is totally inaccurate now. To keep yourself from getting bored, try out new weapons in the adds in the areas. Put on a memory of Gheleon and just pick up tons of chests. You'll rack up a lot of relic irons, glimmer, maybe get new ships, and sometimes I get 3 strange coins or engrams.
