Can we make sona a little better please?

Can we see some small buffs on Sona? Mostly around her mana usage, especially in the early to mid game. Anyone who has played her knows that Sona burns through mana like it's going out of style. Her Q is well costed, it's not insanely high but it's not free, so you can run out of mana if you are just spamming the thing everytime it's up. Her other abilities though, are huge mana sinks for rather unimpressive returns, especially during the early game when Sona won't have the cash to buy a bunch of mana regen items. I do understand you don't want her to be unmovable from lane, but it seems rather insane that she often needs 3-4 mana items to stay active (not constantly running out of mana) during the mid to late game.

If the game goes long enough, I personally end up with + + + maybe . What makes that really disappointing is that without tear i still often find myself running low on/ out of mana if i have to chaingun spells for more then a few moments. So with 275% - 325% base mana regeneration i can still find myself unable to cast spells for prolonged periods of time. Again keep in mind that this is 2-3 items out of my build, 33-50% of my full item build is mana regen and i STILL have mild mana problems. If we include Tear in the list, which already means that Sona is behind on building the items she wants/needs, that means that a Sona player has to dedicate 50%-66% of her inventory to mana regen items. (As a quick aside, Sona would likely be in an even weirder spot if wasn't a go to item for basically every support character)

I'm not even talking a huge decrease in mana cost, maybe something like 10 mana less to cast her W and E. Enough of a decrease that a "good" Sona player can squeeze 1-2 more spells out before running out of mana, but not enough of a decrease that Sona becomes an unmoveable/ inexhaustable wall of healing/ protection for her allies.
