Sona: the weakest in game
As someone who has played Sona constantly for a couple of years now, it is pretty obvious she has gone downhill. She basically has the lowest armor, magic resist, and movement speed in game. While her damage is fine almost everything else is not. Her heal/shield, movement speed ability, and ult are all pretty lackluster. While she does not need an extremely strong buff, when compared to other supports she is in desperate need of tweaking, but mainly in base stats. Also pretty much any champion can one shot her, so if you want to play Sona you have to be a god at dodging.
