They have heard your plea and even went back in time to answer it. :P
Sona
Sona’s planned Gameplay Update is currently a bit more surgical than most – she’s got several existing strengths and high points that players love. Specifically, we’re currently exploring ways to make the choices attached to Sona’s basic abilities more exciting and looking at more satisfying uses of the power currently held by her auras. Ultimately, we want to condense Sona’s power into actions that create skill expression for Sona players, greater clarity of interaction for allies, and have possible counterplay for opponents. Doing so will allow us to create more meaningful moments for players with a champion that is still Sona, but with bigger pay-offs and a lot more to care about from moment to moment. Source
