Dear Hooligart,
I really don't get why you have changed mythic maidens' ability in the middle of Colosseum. Neither the strength, nor the behavior of the abilities are the same. Poor Yakuza got totally useless. Just like you, knowing your enemy, walked into the arena confidently with a pitchfork in your hand, then somebody run after you, and changed it to a spoon. You might really have left some time for us to get used to it.
But at least we can save some time in the World Bosses, as it is impossible to make any further progress, so it is pointless to play.
