Falls ihr wissen wollt wie ihr die witchwood packs maximieren könnt
https://www.reddit.com/r/hearthstone/comments/86t8uf/since_a_lot_of_people_seem_to_be_somehow_confused/Part 1: From March 27 to April 9, each quest completion also awards a pack. Quests assigned before this period also count, so delay completing quests assigned on March 25 and 26. This way, you can complete them sometime during the March 27–April 9 period, and get packs from them, too.
Part 2: [Unconfirmed] The 3rd, 7th, and 10th day of the event (March 29, April 2, and April 5) may guarantee the packs awarded will be Witchwood packs. If so, delay completing your quests assigned on [March 27 and 28], [March 31 and April 1], and [April 3 and 4], to complete them on the Witchwood days instead, in addition to the quests assigned on those days. This could maximize how many Witchwood packs you get in total.
