Sona, can we get some non-damage focused buffs please?

So once again asking for some real buffs to Sona. Can we seriously address just how annoying her kit is to play with. Your damage output is based entirely around one spell, making it almost impossible to win a fight you didn't start way ahead on or finish in the first volley. Her heal/shield is a mana sink in the beginning of the game, often requiring 2-4 uses to offset a single poke from an enemy. Her movement speed buff is a joke. A 1.5 second movement speed bonus does basically nothing in regards to getting your team where they need to be. Even her personal 3 second movement speed bonus does little to deal with her innate lack of mobility, this issue is only made worse when you notice that the vast majority of characters have either a higher base movement speed then Sona, or a gap closer that they can use to negate her boost. On rare occasions we have characters with both a markedly higher base movement speed AND a gap closer, making it nearly impossible to escape if they get even remotely close. All of this is only made worse by Sona's heavy need for AP. Unlike many other support champions, Sona just starts to fall apart if you don't build a mass of AP, on her.

Can we please get some real buffs to Sona:

Be it come in the form of lower base cooldowns. No more "welp i got them to 5% and then they turned around and blew me up because i have no damage outside of Q, can't heal very well, and most the champion pool can outrun me with ease... Even though i'm rocking 45% CDR". It also provides a bit more of a skill floor where good Sona players will manage their mana, bad ones will spam run OOM and be useless for long periods of time.

Maybe introducing items that focus around utility mages. Say items that give marked bonuses to heals/shields given to allies; items that function as mana or health regeneration auras but only work with an ally within X distance of the player. Basically items that remove the need for support characters like Sona to need to build like AP mids with limited income. While also being of limited to no use to other roles.

Final suggestion would be to make Sona's E (the movement speed ability) have a secondary effect that negates slows, and roots (maybe stuns??) while the champions are effected by it. The spell already has a 12 second base cooldown, a requirement of close proximity to Sona to function, piss poor scaling/ratio, and a VERY limited duration.
