Best support?

Best support for me is lulu

I really like the tank ones like nautilus and blitz, but i really enjoy playing with the healers like yuumi, soraka and nami

It depends on what you mean by support. I have two distinctions:
Full support and DMG support
For me the best DMG Support is Brand. Thanks to Stun it also manages to help you in difficult situations
instead the best full support is yuumi

tresh... it made me cry several times

I love karma so much, she is my main supp

maokai, just because of his passive innate heal. stack MR and hp and you're solid
best "default" support = soraka
yumi and pyke good too, but soraka in past be monster in this. thanks rito for wounds

Soraka is my top pick as support.

yuumi heals more than nami is her career

Imo Rakan the best you can everything

The best one would be Lulu imo, following Thresh, Braum, Leo.
