Disclaimer; Yes, i did just lose a game as Sona support and i'm pretty annoyed. Yes i know i probably shouldn't do this but hey, gotta vent somewhere.
I wish Sona didn't rely so heavily on an offensive Rune setup to do damage.
I wish Sona wasn't one of the easiest champs to kill in the game, or at least had the power to back up that weakness *in her kit*.
I wish her heal didn't cost 100 mana, or healed more early on.
I wish she had more agency in lane.
I wish Sona had a stronger early game, and less of a godlike late game.
I wish some of her ally-oriented power went back to herself.
I wish i didn't have to wait for lvl 6 for a hard CC.
I wish her base MS wasn't that damn low, even at the cost of losing her current E.
I wish Sona had established lore.
I wish she could reliably be played mid-lane as a mage as well as a support.
