I personally think that this event is pretty well balanced and positive for a wide range of players. You can get Tiny Tim by just doing your skull dungeons every day for a week. The grinding rewards are on a small enough granularity that people who don't even grind can get some rewards. And the clan ones are more hardcore.
25 times through a dungeon, overlapped with some of the achievement characters, and the ability to triple up the runs means that even someone fighting manually could get some rewards. Good job devs.
