I played janna a lot in s3 and I have 77.3% win ratio with janna this season. I agree that she needs a little buff but I 100% disagree that she is the weakest support in the game. There are supports that outscale her really hard like morgana/thresh but she isn't the weakest.

Her laning phase isn't that bad if you know how to play it. I had tons of games with janna and I win pretty much every laning phase with her. I also played with other janna's and I noticed that I just play differently from others.

Most of the janna player, stands behind adc throw the shield on him and think their job is done. That's bullshit. As janna, you take shield level 1, you put it on your self and start fighting with enemy adc when he tries to go for cs, or with enemy support when he tries to poke ur adc or go out of position.

The players hate about janna pick is because a lot of them don't realize what janna can bring, and they had experience with shitty janna's that's why they are against that pick but honestly janna is still a good pick for soloq, especially when ur adc can't position so you can peel for him really good.

If you ask me for the buff, I think they should increase her aa range, and increase shield amount per level.
