Just wanted to say I love the idea of the quests, but dislike it being all or nothing.
Unless uncompleted quests freely reset at the end of the season, and you preserve your progress, it'll be next to impossible for a "normal" player to do.
I'd greatly prefer it being 1 quest / 1 item as opposed to 10 quests / 10 items.
Regardless of what you do, its exciting seeing your plans for the future! Thanks for sharing!
