So in trying to understand the mass exodus to the Ark server by Cohorts and the rest of the more "regular" players, I found that a key factor in the decision came from their Kin/Tribe leader when he found it difficult to win in a raid versus raid situations where I was concerned, and was very frustrated with lockups, reload times, and the ultimately his death when he finally realized exactly who it was shooting at him.
I was able to obtain the video of the day in question if you're interested in watching....... enjoy!
