How are you doing on World Bosses?
Lol, this “Event” gets max. 5min of my time every week..
Currently I’m at 8-8-8-8-12(Dark). Could do 1 or max. 2 more Stages each, but as the crappy rewards (rare Cards) wouldn’t be any helpful at all, I’ll keep ’em for later.
Only usage I could imagine (esp. Packs, when you can choose the card out of a selection) is for solving some of the early time-consuming Event-Quests quicker (Find 160 event rare cards / Level Up event rare card to lv 5 / ..).
