What amuses me more and more as these threads go on, is the amount of people who must be coming to these forums with no idea about this current power levelling option, and then going "Oh wow, gonna jump on that train before it leaves the station forever".

It is only helping to increase the amount of people doing it, but not much you can do about that now.
Unlikely. They'd have to be completely blind not to realize what's happening in some of the camps and dungeons.
