Strongest Support Champions in League

[Kini]

What's the strongest support at the moment ?

I saw that Bard got such a nice buff recently but i'm still wondering if the meta engage support is really off ?

Lulu is still clearly, wont talk about Yuumi for obvious reasons

Swain and Xerath

 

[Heaven Trampler]

Blitzcrank and Rakan are good , especially in lower ranks.
