I hope they aren`t. Since EOP only has two paths. It would be a real pain to do it multiple times for only the challengers rewards. Since only the two first runs (assuming you do a different path the second time) will give you the EOP rewards itself.Plus I always like some of the act challenges, or something simple but fun like the Realm of Legends challenges which you can do with a couple of revives that are expiring just to have something to do.Eventhou the majority should still be VERY challenging.
To clear up any confusion:
