They probably meant it's "easy" in the sense that it's easier to finish/doesn't require a lot of time -- just 20 floors and only the last 5 are more of a challenge (compared to past UTC events with 100 floors).

I think it's RNG, my lv 80 Hakata sometimes managed to make it through without getting hit/losing troops and other times the enemies really loved targeting him :/
