Just a minor change request. Right now it's possible to roll several of the “Complete X amount of activities” activities, which ends up kind of bottlenecking the activity quests.
As I understand it, the one requiring you to do 10 activities for a moonshard+tickets is a repeating daily one. Keeping this as a guaranteed daily is good! I just think if you have this one active you shouldn't also get a second activity requiring you to also do 5-10 activities as that narrows the pool of activities you can even do to complete these quests.
I don't think there's as much of an issue with having the “mine X amount of times” or “fish X amount of times” type of activities as stacking ones since those don't put you in a lockdown as badly. This suggestion is purely about this one specific activity.
I hope this post made sense. I feel like I typed the word ‘activity’ way too many times.
