Sona playstyle changes
Ok quick disclaimer: I am making this post mostly because of Sona's new ultimate skin, I main support, and used to play quite a bit of Sona, got bored with her, and started playing other supports. however now I have decided to play her some more, and am a little annoyed at her new playstyle.
Sona's play-style, at least in my mind, is one where she buffs, heals and peels for her ADC. She is meant to be a champion that requires allies to be near her to be effective, rather than one that can roam by herself. Her (Q) Hymn of Valor is meant to be simply lane poke/a good damage buff for her ADC, (W) Aria of Perseverance is meant to be a heal/protective measure, and her (E) Song of Celerity and engage/peel measure. What she seems to have become is another version of an Ap burst mage. Her (Q) plus Power chord AA does a ton of damage, while her (W) and (E) just can't compete. The basic issue is that Her (W) is on too long of a cool down, does not do enough, and costs too much mana. What most players do is end up maxing her (Q) first for damage, and forgetting about her (W) until mid game, when she has enough mana regen for it to be a strong spell.
Ok now my suggestions: Take Sona's (Q) Hymn of valor, and make it do less damage(and when i say less damage I mean a LOT less damage), while strengthening the damage buff, perhaps changing it to a flat damage buff rather than the basic attack damage increase it is now. Her (W) Aria of Perseverance, simply needs to be less exhausting to use, lessen the cooldown and lower the mana costs. I would also increase the AP ratios a bit, but this is simply to offset her (Q)'s damage nerfs. Honestly I beleive her (E) Song of Celerity is where it needs to be, a solid, but not OP speed buff with multiple engage and peel uses. Ad again her (R) crescendo is a solid ability, allowing solid plays in teamfights, but not being a ridiculous amount of CC.
Tell me what you think, if there are any changes you think would benefit her, again this is just my opinion, as a Support main i like carrying my ADC, not the game, and playing Sona recently I have found myself doing the Latter of the two.
Anyway please have a great rest of your day, and thank you for any feedback you can provide!
