The new icons look nice.
I don't have access to the PBE, only what I can read on newsoflegends. Is rework Sona really that good for team fights? The way I see it, she's just a multifaceted Thresh lantern at this point, and if a support is weak lane phase, what kind of a support is that, really? Lulu has Pix, Soraka has the bananas that shorten her heal's cooldown, and at least Thresh can throw his lantern to give a shield. I understand how her lantern-ness would be good in team fights: people run past her, and they get the buffs, but how many times does she have to die in lane before team fights start happening?
Interestingly enough, I think that Sona's teamfight counters will be teams with AoE Clusterf***. Because her team needs to be pretty close together for her auras to work, and some teams would love for you to be placed all in a similar spot.
Morgana, for example. Or Amumu. Or Anivia.
