Best Support?

Honestly, it depends on what you like and whether it is useful for the team. Each champion is good in its own way.

it depends on your adc, as i play main adc lane, and adc legends, and from my experience some supports work better with some legends than others. id mainly play supports with hooks, such as thresh, blitz or even leona. i dont like sona that much, id rather a more dmg oriented lvl 1 support

From my point of view Janna, she's my main, I've got with her over 280k points

I'd say braum is the best for support. I honestly think it depends on the player

my opinion for best support is Sona and Nami, i love both of them

Best support pyke / zyra / braum. Of course Sylas is kinda good but play Zyra the most please please for me

It depends on your play-style.
If you like to help, heal, shield your teammates go for:
Soraka, Janna, Sona, Lulu, etc.
If you want to deal some true damage to enemies go for:
Brand, Pyke, Sona (again, yes... she can deal damage too), etc.

You should try ezreal support, he is useless !!!!!!!!!!!!!!

I am bronze 3 for about 2 years and a half. I am not very good

I think the best support is Morgana or thresh (I don't know how his name is spelled)
