@Meddler, Reasoning behind Sona Changes

A couple months ago there were several changes to on PBE that were eventually abandoned. It appeared the community did not care for the reduced range of the aura's and that they dramatically altered her play-style as a support.

Now the aura ranges are being increased, but her early game appears to be slightly weaker even though she does appear to scale a bit better. Notably, her ultimate changes will alter her later game.

Support is my secondary role and I primarily play Sona, so I am curious as to the reasoning behind the changes and if it is likely that these changes will go live in one of the next patches. Does riot think Sona is in a bad spot?
