Best Support?

Karthus > Morgana > Blitzkrank.
Karthus is the best to keep the opponent back. So it disrupts the opponent's farm and causes a lot of damage. When his adc attacks, he will be stronger and the enemy already punished

I think thresh is in a pretty good spot right now as he has always been. Ofc if the player is bad not much can be done.

I think Braum and Bard is one of the best Supporter for gank safe your lane and get kills.
Otherwise Leona or Lulu for Lategame

In my opinion Thresh is god if u can play as him, that champ can change game

Like support, i played just Thresh and Blitz i think both of them are too good like support.

Teemo
Sona
Morgana
Lux
Velko
Malphile
There are heros, which i ussually use when play in support position.

The best support(s) has to be Soraka and Taric. They're both very flexible and have easy ways to escape the enemies. You can also be of good use to the rest of your team aswell.

I think the best support is janna is by far and already for several seasons

For me :
1 - Thresh
2 - Blitzcrank
3 - Leona / Janna

There are a lot of supports who are good in this meta but the one that I like most is lux because you also have a ton of aoedmg.
