This thing takes too long too and just sucks up coins. Every game should give at least one key but I’ve had ones that have a lot of cards but won’t give even one key.
I pretty much do all the event quests. Why not, they are easy, even the loss suits/lost coins scavenger hunts.
However the only event quest I absolutely refuse to do is the Lost Keys. There’s no strategy, no tactics. It’s purely random.
So, No to lost keys!!!
I definitely see your point. It’s aggravating losing so much coins for nothing. I’ll avoid it next time.
