Heh, I was just coming here to post about how there's certain maps that just Will. Not. Clear. Mine happen to be the advanced dragon maps, which is more frustrating than any of the event maps because they're so simple and there's almost nothing that you can influence on them. I finally cleared the blue dragon map Tuesday, and I've been plugging away at the yellow dragon map today...though I think I've had my final shot at it for this week since they'll change over before I can build up another 80 stamina.

It helps to consider FKG as entirely a strategic resource-allocation game rather than a game with both strategic and tactical aspects. You can't control how the battle goes, but you certainly can control how you prepare for it.

But there's no need to throw a temper tantrum at the game, it's just luck. Luck is why they give us such a long time each event to clear eight maps. You still have plenty of time to clear it. You aren't 'wasting' your stamina trying to clear a map you haven't gotten yet, you'd have to spend it on running one of the maps anyway.

No map is impossible to 3* unless you just started playing. Did you read ANY of the posts that describe in detail the MULTIPLE ways to clear all the event maps?
