Imo, pure support teams beat all other pure role teams cause of support versatility.

Sona is still quite good. She sustains less, but that double aura buff is nice for turret diving and ups her survivability a lot. I see some people talking about AA on Sona. For mana issues philo+chalice is much better. It's cheaper, gives gp5 and some survivability too. Sona is full support hero and should be played as one - meaning not taking CS, warding everything, getting gp5 and if the game lasts aura items (Aegis is a must unless your tank is taking it).

Karma is UP on 5v5. People who claim she's OP have no idea what they're talking about. She fits the current meta game poorly. You don't put her with AD carry bot cause other supports do her job better and you don't put her mid since other AP casters have more burst/DPS and more use of getting to lvl 6 asap. Well, she might be ok as support since the sustain nerf, but I'd rather have Sona/Taric/Janna/Alistar. No inbuilt survivability and short range is bad for a support (and AP caster) and she's the only one with that problem. Not to mention lack of hard CC.

I heard some Karma buffs are incoming (something about Spirit Bond, but I might've misread) and they're well deserved.
