Okay so we have all seen with the health update how quickly these world bosses are falling now. Which is great because some were coming down to the wire to get them beat. Now here is the dilemma sooner or later both bosses are going to be defeated at the same time because of the health update improvement. So my suggestion again is once a world boss is defeated the next one should open up. Just as regular bosses do so long as their not laying dead from the last time they were killed. Get rid of the Friday/Early Saturday morning waiting for another one to refresh. Just go ahead and let them activate on their own.
