Still looking for some QOL buffs to Sona

So i i will admit with the changes in this recent patch Sona has become much more reasonable to play. The bonus mana regen and the mana regen bonus on have done wonders to helping with her mana issues based around her heal. With this said, i still feel like she has just a hair to much built in weakness. The combination of low base movements and small range on her utility, leaves her feeling wanting as a support character. Would it be possible to see a small buff to her utility range, like say 100-150 more range? This would allow Sona the ability to help her team mates with a bit less risk of getting caught out, however the range is still short enough that Sona is by no means always safe and detached from combat.

Sona is still one of if not THE most fragile characters in the game. This aspect coupled with her low movement speed, low utility range, lack no non-ultimate stun, and lack of reliable gap closer makes Sona feel a little to risky in most situations.

Finally since Sona seems to be a champion who is based more around doing something a lot and with a lot of team mates, is it possible to see a reduction in the base cooldown of both her heal/shield and her movement speed bonus? Both of these abilities still feel like they are heavily gated in use till many levels have been put into them AS WELL AS having 30% or more CDR. The heal and shield might be as simple a fix as simply upping the time the shield is active to something like 3 seconds, thus preventing spam healing but still making the ability as a whole feel impact-ful. The movement speed boost really either needs to have a lower base cooldown, or a passive movement speed bonus for Sona. Either of these changes would help fix a running issue on Sona where you simply can't outrun almost every other character. Not just trying to escape, but also trying to chase down targets usually ends in failure. Sona is just too slow to run towards or away from people, and her movement speed bonus is on a longer cooldown then most other characters gap closer.
