Rubick Guy will prob hate me for this suggestion: What if Sona's buffs worked like Fiora's Ult?
Inspired by this comment about Sona and positioning.
So Sona would passively have her aura circle around herself with 4 fields like Fiora's ult. When she uses an ability she colors the aura blue/green/purple and the nearest guy on that quarter gets a buff. The quarter disappears. Only procs on active or when 'touching' them with the outer edge. So if two people are on one field and Sona has no Mana any more, she has to distance herself, walk around her ally and walk back to proc another field. If Sona procs all four fields she gets Super Saiyan stuff, like her current passive on steroids or something. Fields reset one by one eventually (or all at once) so she has to keep up the beat(ing) to get the spiky hair.
Uhm ... gives her a really high skill cap, maybe? She would keep the current "last spell gives bonus effects" effect probably, after all. Might make Riot like her since she's flashier so they stop nerfing her immediately every time she's as good as any other Enchanter.
Edit: Could also be three fields because three basic abilities, positioning your active in a quarter pie might be too hard, and so it looks visually different from Fiora's ult.
Edit: Could also be five fields since you can bump people. Or three to five fields increasing with level? Eh.
