Yeah, I personally think they fucked it up in the first Destiny because the first year was great but the years after they messed it up so it was something like 1 challenge, 2 masks and then you'd have to buy eververse to get the rest.
With effectively a 2/3 month cycle for next available content alongside DLC, it sounds good as The Dawning looks like a decent event (don't think I ever did the first one in D1), but hoping a light level increase comes near it, even if its DLC.
@Baabcat, haven't seen anything being mentioned about SRL. I wouldn't be surprised though as we've not had it for a while.
