about sona PBE changes

Song of Celerity (E) haste % for allies increased from [10/11/12/13/14 (+3% per 100 AP)] to [10/11.5/13/14.5/16% (+4% per 100 AP)] haste % for Sona increased from 10-14 (+3% per 100 AP)] to [25% (+4% per 100 AP)]

i dont know what most ppl think about this changes but i wanted to ask if this is actually a good solution to one of sona's problems, her lack of mobility really make her unable to survive mostly anything and this makes E worth even putting a point early on, but i also wanted to address the following idea

disclaimer: i know most ppl dont care about sona, and that riot dont read the forums but just hear me out a sec.

i think sona's mayor issue comes from her ult passive, i get that it is there to make her scale very well into the late game, but it sacrifices so much for the early game in a world of high damage that she dont get to that point unless playing very passively or being a sona taric bot lane.

what if we remove the colddown reduction passive of her ult and then make changes to her abilities, for one auras are a cool idea but Q aura is a worst nami E and the shield from her W is just completely inconsecuencial, and the have to be because of how spammable the skills become late game, but if that gets resolve riot could make auras range slightly bigger and make it so Q aura gives allies autos a smaller but consistent magic damage on hit but only while in the aura, the shield from W should last 1 second but its duration refreshes as long as the Ally remain in the aura, same for the movement speed, with these changes plus adjusting some number dont you ppl think she would be more interesting to play? she will still have a glaring weakness of forcing allies to want to stay together for the buffs while also swifting some power from spammable abilities to more consistency and impact on each
