Was Ao Shin not fun?

I was watching Angry Joe interview Paradox and one of the devs was talking about how announced games got cancelled. What Paradox does is they currently try to get the proof of concept right before they announce the game to make sure the core gameplay is fun because not doing that had bit them in the past. So they had to cancel games they should not have announced.

Did something similar happen to Ao Shin? Did you guys think you had a champion but after playing with him for a bit you realized he wasn't fun to play for some reason?
