What Sona really NEEDS
As someone who mains Sona
1 thing stands out above all things about Sona. She is in dire need of a buff to her W, the rest of her kit is fine, so what if her poke is weaker then say.... Lux, Annie, Morgana, and other Mage type supports, Sona isn't supposed to be a MAGE support, she is supposed to buff and heal and SUPPORT her team. I don't get why people are complaining about her dmg when she has quite good poke already. As stated before, what Sona needs is a buff to her heal.

Edit: P.S. Even Taric outheals Sona.
New Edit: Figured this also had good points.

Fact 1. Sona has a lower winrate then other supports that are played in almost every match now.
Fact 2. Her poke is fine and isn't too hight or too low but the rest of her kit doesn't make up for how low it is especially how low her heal is. (her ult is strong but has a long cooldown even at 45% CDR)
Fact 3. A lot of teams don't want Sona because she doesn't poke as well as Morgana, Lux, Zyra or Any mage support, She doesn't heal nearly as well as any other healing champion like Raka, Taric, Alister, Nidalee, and she can't CC as often as many other champions, Lux, Morgana, Alister, Shen, Leona, and finally she can't Tank like Taric, Alister, Leona, and Shen.
Fact 4. People who do generally play her or want her in party only want a Sona for the DJ skin.
