Listen I just want the Morrigan helmet so badly but it is in one of two events I missed. Hopefully these items can return as weekly rewards? If we do recycle stuff into weekly rewards maybe those who already had it can get a challenge swap or double xp, that way I can get the helmet that haunts me and those who got it get a reward too!
Alternatively, imagine this(probably unrealistic): Upon completion of a battlepass (or some other thing equivalent) you receive an event rewind, you can pick any event and for one week you will get that event pass back and challenges to match. this can also be cool for if someone wants just a bunch of xp with the progression coming in the future!
