Under this system, if you camp a spawn, you will still indeed have the advantage, but it won't be a foregone conclusion as it is right now. If two raids are camping, it won't matter which showed up first and spent the most time there (afk!), first try will go to the raid that acts quickest. Theoretically, one raid that camped but isn't on the ball could lose out to a raid which has only just shown up but is ready to go.

Really, nothing short of a rotation will prevent camping the mob before it is going to spawn, but at least this way the camp need only commence before the variance window opens, not 4 days before.
