Riot have not mentioned soraka in any discussions at all since the nerfs that were meant to be power neutral for support, but really had no direction and hit her overall, with top still being better.
Can soraka have rejuv duration back to 5s, it was a really random nerf that made no sense, making the supposed compensation on w for q healing going down completely useless
Now that Soraka top seems (fingers crossed) to have been addressed we're putting some power back into Soraka in 10.6. Targets there are Q heal and MS bonus both going up a bit, with the goal of getting her support impact somewhat higher.
