The idea that this is good for the game and a way to level the playing field is a not accurate. A low level player will not close the gap by completing this one event. Sure they will get a nice jump in stats, but to close the gap you'd need to complete many of these style of events. With the xp gained you'll quickly be in the same situation as the higher level players and not be able to complete the event and there will still be a gap in stats.
