My thoughts. After the first random VIPs are selected. If you kill the VIP you should obtain the VIP status. (It will pop up in everyone's news feed) that way there's more inscentive to take them out.
It wouldnt work out if the other clan knew who was VIP...the VIPs would be a target and they wouldnt get a chance to do anything...
Nope. Spies are already war kings. "VIP" will just render war leaders and trackers nearly unable to be tracked, as those folks would normally be the folks most often nominated. Keep it fair and equal. This idea makes spy-builds less valuable and skews tactical advantages.
I think some people have to much time on their hands and should leave game updates and add-ins upto the devs. That's one of the dumbest ideas I've heard yet.
