Riot, one day you'll finally come to the conclusion that Sona deserves to de disabled in ARAM...

...and let's hope this day is as close as possible, because all those nerfs aren't doing anything to her. Her whole kit is already broken as it is on top of the fact that it looks like it was purely designed to be used on howling abyss, at this point number changes/nerfs won't do anything to her. The only thing that could put her in a somewhat balanced state would be to utterly change parts of her kits mechanically, and we all know that you'll never put as much effort into a single champion for a mode that you actually care for only twice a year or so (excluding the "recent" addition of "balance" changes to specific champions, who are very unstable themselves) so, for the love of god, just disable her.

Don't listen to her mains. Don't listen to ARAM account users. Don't listen to people who play ARAM like once a month. She has been broken forever on ARAM and you know it. You've nerfed her to the ground and she is still the most broken and you know that too. YOU KNOW the solution. YOU KNOW it must be done. So just do it and improve the whole game mode by doing so.

Edit: Oh no. The Sona mains...The ARAM accounts... they are here! FLEE FOR YOUR LIVES, BEFORE THEY SHATTER EVERYTHING THAT IS BALANCED IN YOUR LIVES!
