The dungeon quest was fun but the only problem me (and some other people) faced was that the reward at last was random. I did that quest 10+ time to get a single light stone. Next time, I want such a quest with guaranteed rewards at a particular number of wins! For example- After doing the dungeon 4 times,the reward is guaranteed light stone!!
Except this and and the monkey part in zekrom quest, everything was fine!
