Why Bard and not Ao Shin?

Well Riot first started off by giving us a teaser about thin new champion. Ao Shin looked amazing and you go and trade him in for this new champion named 'Bard' Why treat us like this? Ao Shin was this nice amazing weather dragon of Ionia now me a stuck with a magical fat guy with a beard and peg legs. I will have a pull down below write a comment and vote of what you think Bard Or Ao Shin Personally i don't think they should let out information on somthing they arn't putting in i understand what they are going through but still. i would have much rather had a big weather dragon then the following : Lucian,Vi,Bard(obviously),Galio,Swain,lisandra,Etc.
