Janna or Soraka
I want to learn and master one of these, which would would be better for low elo? (Bronze-Gold)
I currently main Lulu and am looking for another support in case shes banned/picked.

PRAISE THE FUCKING SUN YOU INFIDEL
I mean if your already playing one ardent champ you should focus on adding a differnet support. you need to have an adaptive pool. My 3 supports are kench, janna, and currently practicing thresh to make him my 3rd. Got a ardent shield support, a frontline tank/peeler, and a playmaker.
While out of the two Soraka because she is the most different from Lulu I tend to agree with Tahmpon, if you have different types of support champions it will mean you have something that covers more strategies and scenarios.
Tbh Neither will be truly learned in Bronze. Janna and Soraka are technically high skill to master. They're easy to use as barrier/shield bots, but that's not their entire kit's potential. Janna can 1v1 most champs in the game after her rework. But..... most lower elo don't build her that way. They also don't utilize her autos correctly, or place correctly on ults. I've had a Janna do better than Zoe at lower elo, because janna could just 1v1 a Jhin, and then used that to build up to a point she could 1v1 the entire team. At one point, she even 1 hit me as Zoe..... with a W and an auto attack, because her move speed was so high that her AD bonus was huge.
Soraka's not as busted, but she too has damage potential on top of healing, and good elos utilize it. Low elos squander it. Go watch a Soraka whose a Diamond sometime go smurf a Bronze game. She'll go 30/0 and do 70k damage and 45k heals.
If you want that style, play Nami.
