Why would you schedule the Dreaming City cosmetic drop rate patch to come out the week AFTER the Shattered Throne??? How hard is it to say to yourself "Hmm, maybe it would make more sense to have the patch come out when the Shattered Throne is available so players don't have to wait an additional 3 weeks to take advantage of it?!" Seriously, who is in charge of stuff like this over there? A bunch of monkeys?
That’s how scheduling pans out sometimes. We couldn’t bring the patch forward a week- would have lost some fixes and tuning in the process. Couldn’t bump curse week out, would have impacted many systems tied to the calendar of recurrence. I agree, it’s a bummer we couldn’t have these both land on the same week, but curse week will continue happening in Destiny 2- it’s not going away. You will have a chance to get the cosmetic next time Shattered Throne is around.
