the aura range is actually okay because the original effects still have the same ranges as before (q beams, w heal, and e speed) but you get an additional effect by touching someone with an aura which is no longer just a small stat boost (q mini sheen, w shield, e uh more speed) so it's not like people have to cluster around you but rather sona has to run around giving everyone on her team a little tap with her aura which is kinda cute :3
also new Q auto hits pretty hard
