You conspicuously left out the DF s1 data that would show a 22% drop in week 1 keys as well. Almost like more people play the first patch of a new expansion than stay for the entirety, as they have always done.
Also important to remember, we now have 10 entire keystone levels missing that are included in data when compared to past expansions. Anyone who could only do a +5 key previously is now stuck in m0/heroic or a delve main.
If you sort out any keys below a 10 for DF s2 week 1 (because they now don’t exist) ‘only’ 1.8 mil keys were completed. Given we’re at 1.75 mil right now, I’d imagine by the end of tonight we’ll meet or surpass the DF stats.
