Sona strength and weakness

So been meaning to put down my thoughts and see how other people think. So i love Sona, and really loved how strong and useful she was before her rework all the time ago. Now i would like to say while saddened by the update when it happened, i don't think she lost to much back then. That said with how the game has developed since that rework took place, i can't help but feel like Sona really needs some power added to her.

Before the rework Sona was by most means "THE LANE BULLY", high damage low cooldown and a pile of stats your allies gained just by existing within about 1000 range of you. The heals she use to give where never super impressive but at the same time the low cooldown and decent numbers made them worth the cost and in some cases it was even viable to make out her heal before her damage ability. Her movement speed ability has never really felt all that strong even maxed out it rarely felt all that impressive to give your team the bonus 20 movement speed.

After the rework, she was much less powerful, she lost her passive buffs so your allies had to use much more limited windows of "power" to get the advantage. Her heal lost a great amount of it's base value and i believe the ratios also took a turn for the worse. I can't say i remember exactly what the ratio use to be, but i feel strongly that it was more then 20% on the heal and 20% on a shield The shield sounds nice but it's power seems to be tied heavily to a fear of abuse with . In reality the shield doesn't give all that much damage negation, and it's duration is laughably sad. While 1.5 seconds is more then long enough in the middle of a team fight, in any other situation it rarely absorbs it's full potential before falling off. In addition to that i believe most people would agree they would rather heal a single target + self for the full amount rather then half of it go to a heal and half to a short lived shield, even if the shield can in theory cover the whole team. Her movement speed bonus still feels like a throw away skill, there never feels like a reason to put more then one point into it since the movement speed doesn't feel like it's enough to effect a team fight, be it in running away from the fight or chasing down a target.

The nail in the coffin as it where, is that since the rework all of her skills gained 2-4 seconds base cooldown. So where before you could machine gun spells and use her passive super aggressively, now it often feels like until you max out CDR you use an ability and then just wait around with your thumb up your butt. It's super frustrating to be in the middle of a battle and know that you are useless for long periods of time and even when you are useful, you often need to be 5 items (Boots, Sightstone, Mana regen + CDR item, Lich Bane, good AP item) in before you have any kind of effect on the battle.

I think Sona needs to be buffed a bit, and it needs to be in ONE of two spots. She either needs to do more damage, so that she regain the title of "THE LANE BULLY", i'm talking damage that makes even tanks go "crap that hurt! Can't let her hit me again". Or she needs her utility numbers strongly buffed. If my poke isn't going to be helpful to the team from levels 3-14, i really need my utility to make up for that. Sona suffers from the issue of if she snowballs she snowballs out of control (huge damage, above decent support numbers) but if she doesn't snowball it's a long slow climb to get the numbers she needs to help her allies. Regardless of which buff she gets i think she would also benefit from lower cooldowns, one offensive ability on an 8 second base cooldown isn't going to win many fights. one low powered heal on a 10 second cooldown isn't going to help keep your ally in lane/ win trades.
