On high duel difficulty (ex. at 500) my npc had 15-20k hp. How could you KO them to finish some quests? You can't, you have to loose a lot of duels with them to bring difficulty lower again, i think this should be fix.
So no soccer event. Maybe consider adding willow baskets? We also need those dreamcatchers to finish a quest so its a good opportunity. And again, those dreamcatchers doesen't exist on newest world to buy them from market.
