TBH the Kayle thing wasn't actually Shurelias fault (not white knighting here just stating fact) she was moved off onto another project before the Kayle rework was finished, thus the person that messed up Kayle was not Shurelia.
I've been watching the info Shurelia has been giving us with keen interest, as a support player myself I do want us to be so much more than just the "babysitter" although at the same time, I do enjoy being able to help my carry be the best they can be without detriment to there farm.
I do worry that we have been getting conflicting information from other reds about Morellos plans for support, moreso for Soraka since its been made clear he utterly hates the champion, the conflicting info is that Supports are being shifted to a more Lux and Morgana model and this is a bad thing and defeats the purpose of being a true support champion.
If anything, Alistar and Janna are the ideal supports to be molded from, Alistar performs admirably well as a tank AND as a support thanks to his utli and great CC, Janna brings a lot to team and can be itemized to become quite deadly but not doing so does nothing to her utility.
Supports should be optionally itemized, there utility should be strong whatever the choice as that is what they do best, however should you choose to itemize the benefits should be worthwhile and not feeling that you are greedily taking farm away for it to be useless.
Just my thoughts on it.
