Here's a thought: What if Ao Shin were not made into a Champion, but an Epic Monster?
Riot stated that one of the big problems with making Ao Shin is his size. Because he's a dragon, he has to be bigger than a majority of the cast, something that causes gameplay issues.
Now, this is just a hypothesis, but what if Riot decided to make Ao Shin an Epic Monster (of sorts) in a future Featured Game Mode? Maybe something akin to Ascension or something like that.
Would that be appropriate for him, Riot? Or do you still want the Storm Dragon to be among the playable roster in the future?
