Sona is an all-around champion... she doesn't need buffs.

She's not made to be like other supports. Or rather, she's made to be too much like them. Her abilities are limited, but a very large range. She has poke, and just damage period, sustain, engage and disengage, and CC.

Now lets say Sona does get a buff. What happens to her? Do you really want one champion overshadowing all others because she's just as strong as them in their core factors? I mean, imagine Sona with the damage of Karma, the sustain of Soraka, the engage of a Righteous Glory or the disengage of a Sivir ult, and the CC of an Alistar. I mean, it'd be pretty OP right?

Now not many people are focusing around her ultimate, but I have seen many posts around her poke, heal, speed boost, heck even saw a few posts on her high mana costs. Maybe its just me, but I feel like if Sona was buffed, she would be picked every single game and contested so hard for a support. The idea of sustaining like Soraka, while still engaging and disengaging like Alistar or Thresh, and poking like Karma or Brand just seems pretty... overpowered. Heck, even the idea of having low mana costs and just spamming all that shit seems scary.

I don't know, what about everyone else's thoughts?

Edit - 67Chrome explained to me a bit why she needs buffs, and I guess I get it... but the main reason I made this post is, it just sort of makes me paranoid. I mean, it seems like if one champion gets buffed because he's being overshadowed, then another champion gets overshadowed in the process, or maybe multiple. And it just seems like making her stronger will make other supports look weaker... especially someone like Annie, where if Sona was buffed too much, would bring everything Annie brings and more. Now she'd be overshadowed.

But, maybe if, like a lot of people say, she got higher base stats and was less reliant upon AP to be useful, she could be more... reliable. Still, that just sort of scares me... I don't know.
